I am using session variable to keep track of items in the cart. I generate a table using loop to display contents of the cart. The code for table is as follow:
<?php
$count=0;
$grandTotal=0;
foreach($_SESSION['cart'] AS $product) {
$table=$product['table'];
$id=$product['id'];
$Name=$product['name'];
$qty=$product['quantity'];
$price=$product['price'];
$total=$qty*$price;
$grandTotal +=$total;
?>
<tr>
<td class="cart_product">
<img src=<?php $i=2; echo "images/".$table."/".$id.".jpg"?> height="150" width="150">
</td>
<td class="cart_description">
<h4><?php echo $Name?></h4>
<p><?php echo "Web ID: ".$id?></p>
</td>
<td class="cart_price">
<p><?php echo $price?></p>
</td>
<td class="cart_quantity">
<div class="cart_quantity_button">
<a class="cart_quantity_up" href="addToCart.php?table=<?php echo $table ?>&action=inc&id=<?php echo $id ?>" id="increment"> + </a>
<input class="cart_quantity_input" type="text" name="quantity" id="qty" value="<?php echo $qty?>" autocomplete="off" size="2">
<!-- <p class="cart_quantity_input" name="qunatity" id="qty"><?php echo $qty?></p>-->
<a class="cart_quantity_down" href="addToCart.php?table=men&action=dec&id=<?php echo $id ?>" name="decrement" > - </a>
</div>
</td>
<td class="cart_total">
<p class="cart_total_price"><?php echo $total ?></p>
</td>
<td class="cart_delete">
<a class="cart_quantity_delete" href="addToCart.php?table=men&action=del&id=<?php echo $id ?>"><i class="fa fa-times"></i></a>
</td>
</tr>
<?php
}
$tax=0.15*$grandTotal;
?>
I am having problem with + and - buttons within a tags. I want to increment or decrement value in input field named quantity. But since i am generating table in a loop i do not know the id of each field. I want to do something like this:
<script>
$(document).ready(function () {
$("#increment").click(function () {
var oldval=document.getElementById("qty").value;
var newval=parseInt(oldval);
document.getElementById("qty").value=newval++;
});
});
</script>
But this method always increments first quantity field in the table. How do i get ids of other quantity fields in the table?
Dont use ids inside loop.Just use class for that>check the snippet for a smaple demo
$(document).ready(function () {
$(".increment").click(function () {
var oldval = $(this).prev('.qty').val();
var newval = parseInt(oldval)+ 1;
$(this).prev('.qty').val(newval);
});
$(".decrement").click(function () {
var oldval = $(this).next('.qty').val();
var newval = parseInt(oldval) - 1;
$(this).next('.qty').val(newval);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table> <tr>
<td>sl No</td>
<td>name</td>
<td>Dept</td>
<td>dummy</td>
<td>dummy</td>
<td>dummy</td>
</tr>
<tr>
<td>1</td>
<td>name</td>
<td>
</td>
<td>name</td>
<td>name</td>
<td> </td>
</tr>
<tr>
<td>2</td>
<td>name</td>
<td>Dept</td>
<td>name</td>
<td> <button class="decrement"> - </button>
<input type="text" class="qty" value="1"/>
<button class="increment">+ </button>
</td>
<td>name</td>
</tr>
<tr>
<td>3</td>
<td>name</td>
<td>name</td>
<td>name</td>
<td>name</td>
<td>name</td>
</tr>
</table>
There are 2 solutions to this problem:
When generating table using php, assign unique id to each row's <a> and <input>, such as #increment_id8878 and #input_id8878. Then when #increment or #decrement button is clicked, operate <input> with corresponding id.
Operate <input> element with jQuery's relative selector.
For example:
$('.increment').click(function() {
var inputEle = $(this).siblings('input');
var originVal = inputEle.val();
inputEle.val(parseInt(originVal) + 1);
});
A jsfiddle is made for the 2nd solution.
BTW, duplicate id should be avoided in HTML code.
Don't use same id for multiple elements instead use class like below
<a class="cart_quantity_up" href="addToCart.php?table=<?php echo $table ?>&action=inc&id=<?php echo $id ?>" class="increment">
same is case of decrement button user class
<a class="cart_quantity_down" href="addToCart.php?table=men&action=dec&id=<?php echo $id ?>" name="decrement" class="decrement"> - </a>
You can bind click event to these anchors and change the quantity in input inside same parent div
$(function(){
$('.increment').on('click', function(){
var $parent = $(this).closest('.cart_quantity_button');
var $input = $parent.find('.cart_quantity_input');
var value = $input.val();
value = parseInt(value)+1;
$input.val(value);
});
$('.decrement').on('click', function(){
var $parent = $(this).closest('.cart_quantity_button');
var $input = $parent.find('.cart_quantity_input');
var value = $input.val();
value = parseInt(value)-1;
$input.val(value);
});
});

I have a table which shows the list of my products and I have used jQuery to delete products without reloading the page, however the updated table doesn't show unless I refresh the page..
I have tried to hide it by using opacity, still it doesn't work..
Here is my php code
<div class="table-stats order-table ov-h">
<table id="bootstrap-data-table" class="table ">
<thead>
<tr>
<th>Image</th>
<th>Name</th>
<th>Availability</th>
<th>Category</th>
<th>Total Ordered</th>
<th>Edit</th>
<th>Delete</th>
</tr>
</thead>
<tbody id="data-table">
<?php
$stmt_1 = mysqli_prepare($link,"SELECT * FROM products");
mysqli_stmt_execute($stmt_1);
$result = mysqli_stmt_get_result($stmt_1);
while($row = mysqli_fetch_array($result)){ ?>
<div class="product">
<tr class="product">
<?php
$sql_img = "SELECT * FROM pro_images WHERE pro_id= ? LIMIT ?";
$stmt_img = mysqli_prepare($link, $sql_img);
mysqli_stmt_bind_param($stmt_img, "ii" ,$param_pro_id, $param_limit);
$param_pro_id = $row["pro_id"];
$param_limit = 1;
mysqli_stmt_execute($stmt_img);
$img_results = mysqli_stmt_get_result($stmt_img);
$image = mysqli_fetch_assoc($img_results);
?>
<td><img src="../admin/assets/img/products/<?php echo $image["pro_image"]; ?>"></td>
<td><?php echo $row["pro_name"]; ?></td>
<td><?php echo $row["pro_quantity"]; ?></td>
<?php
$sql_category = "SELECT cat_name FROM categories WHERE cat_id = ?";
$stmt_category = mysqli_prepare($link, $sql_category);
mysqli_stmt_bind_param($stmt_category, "i", $param_cat_id);
$param_cat_id = $row["pro_category"];
mysqli_stmt_execute($stmt_category);
$result_category = mysqli_stmt_get_result($stmt_category);
$category = mysqli_fetch_assoc($result_category);
?>
<td> <?php echo $category["cat_name"]; ?> </td>
<?php
$pro_ord = "SELECT COUNT(*) AS total FROM order_details WHERE pro_id = ?";
$pro_stmt = mysqli_prepare($link, $pro_ord);
mysqli_stmt_bind_param($pro_stmt ,"i", $row["pro_id"]);
mysqli_stmt_execute($pro_stmt);
$pro_res = mysqli_stmt_get_result($pro_stmt);
$pro = mysqli_fetch_array($pro_res);
?>
<td><?php echo $pro["total"]; ?></td>
<td><span class="badge badge-success"><i class="ti-pencil"></i></span>
</td>
<td>
<button class="remove badge badge-danger" onclick="delete_data(<?php echo $row["pro_id"]; ?>)"><i class="ti-trash"></i></button>
</td>
</tr>
</div>
<?php } ?>
</tbody>
</table>
</div>
And here is my JQUERY code
function delete_data(d){
var id=d;
if (confirm("Are you sure you want to delete this product? This cannot be undone later.")) {
$.ajax({
type: "post",
url: "products.php",
data: {id:id},
success: function(){
$(this).parents(".product").animate("fast").animate({ opacity : "hide" }, "slow");
}
});
}
}
And here is the delete code
$pro_id =$_POST['id'];
$delete = "DELETE FROM products WHERE pro_id= ?";
$results = mysqli_prepare($link, $delete);
mysqli_stmt_bind_param($results, "i", $param_pro_id);
$param_pro_id = $pro_id;
mysqli_stmt_execute($results);
You need to be more specific when you targeting the div you want to refresh, for example:
success: function(){
$("#div_id_you_want_refresh")
.load("your_entire_url" + "#div_id_you_want_refresh");
}
You can pass this as well inside your delete_data function where this refer to current element clicked i.e : your button . Then , inside success function use this to hide your .product element.
Demo Code:
function delete_data(d, el) {
var id = d;
if (confirm("Are you sure you want to delete this product? This cannot be undone later.")) {
/* $.ajax({
type: "post",
url: "products.php",
data: {
id: id
},
success: function() {*/
//use this then remove closest product tr
$(el).closest(".product").animate("fast").animate({
opacity: "hide"
}, "slow");
/* }
});*/
}
}

I am trying to figure out how to submit button with two actions based on dropdown list that I get from MySQL. One is for updating to database and then proceed to nextpage while the other actions is to proceed to specific page. I've tried all the solution but most of them only has a few dropdown menu, mine have 40 menus.
This is my JavaScript
<script type='text/javascript'>
$(window).load(function(){
//$(document).ready(function() {
<!--To Enable button "MULA"-->
$('#lst_respon').change(function() {
if ($(this).find(":selected").val()!='11') {
$('#button').attr('disabled',true);
} else {
$('#button').removeAttr('disabled');
}
});
$('#lst_respon').change(function()
{
$('#form1').submit();
});
});
function changeTextBox()
{
var val=$('#lst_respon').val();
if(val==='11')
{
$('#value').prop('disabled', true);
}
else{$('#value').removeAttr("disabled");}
}
</script>
And this is my HTML
<div align="center">
<table width="60%" border="1" class="zui-table">
<thead>
<tr>
<th colspan="3" align="center">Status</th>
</tr>
</thead>
<tr>
<?php
$smt = $conn->prepare('select * From lookup_caraterima');
$smt->execute();
$data = $smt->fetchAll();
$smt2 = $conn->prepare('select * From lookup_kodrespon');
$smt2->execute();
$data2 = $smt2->fetchAll();
?>
<td width="253">Cara Terima</td>
<td width="5">:</td>
<td width="164">
<select name="lst_cterima" id="lst_cterima">
<?php foreach ($data as $row): ?>
<option value="<? echo $row["kodterima"];?>"><? echo $row["jenis"];?>
</option>
<?php endforeach ?>
</select>
</td>
</tr>
<tr>
<td>Kod Respon</td>
<td>:</td>
<td>
<select name="lst_respon" id="lst_respon" onchange="changeTextBox()">
<?php foreach ($data2 as $row2): ?>
<option value="<? echo $row2["kod"];?>"><? echo $row2["kod"].'- '.$row2 ["Keterangan"];?></option>
<?php endforeach ?>
</select></td>
</tr>
<tr>
<td><label for ="sebab">Sebab</label></td>
<td>:</td>
<td><input type="textbox" id="value" size="100" disabled</td>
</tr>
<tr>
<td colspan="3" align="center"><form name="form1" method="post" action="main.php?load=4&SerialID=<?php echo $noSiri; ?>&month=<?php echo $monthA;?>&year=<?php echo $yearA;?>&tab=A">
<input type="submit" name="button" id="button" value="Teruskan" class="myButton">
</form></td>
</tr>
</table>
</div>
For an automated solution to submit a form based a dropdown selection, you could try using the data attribute, something like:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script>
<form id="tester">
<select name="test">
<option value="best" data-instructions='<?php echo json_encode(array('action'=>'page1')); ?>'>Best</option>
<option value="rest" data-instructions='<?php echo json_encode(array('action'=>'page2')); ?>'>Rest</option>
<option value="guest" data-instructions='<?php echo json_encode(array('action'=>'page3')); ?>'>Guest</option>
<option value="lest" data-instructions='<?php echo json_encode(array('action'=>'page4')); ?>'>Lest</option>
</select>
<input type="submit" name="submit" value="SUBMIT" />
</form>
<script>
$(document).ready(function() {
$('#tester').submit(function(e) {
// Stop form from submitting
e.preventDefault();
// Get the select dropdown
var thisSelect = $(this).find('select[name=test]');
// Get the value
var thisVal = thisSelect.val();
// Get the options separately
var thisOpts = thisSelect.children();
// Create a holder
var thisData = {};
// Loop through the options
$.each(thisOpts,function(k,v) {
// Get the current value
var currVal = $(v).attr('value');
// If the current value is the same as the value selected
if(currVal == thisVal) {
// Get the instructions from the option
thisData = $(v).data('instructions');
// Stop looping
return false
}
});
console.log(thisData);
});
});
</script>
On submission, the selection will give you an object that you can use to instruct how to submit the form:
// thisData.action
{action: "page2"}
Hello I am wanting to echo a PHP Variable to a buttons value then send the buttons value to an input text. I was able to echo the button with the variable but when I click the button it does nothing. I'm not sure why, because when I do this without the PHP just the script, and inputs it works perfectly. I am just missing something I know it, I can't find much info on how to pass php to a button then pass the button value to an input text.
Here's the script that passes the button value to the input text:
$( document ).ready(function() {
var $theButtons = $(".button");
var $theinput = $("#theinput");
$theButtons.click(function() {
$theinput.val(this.value);
});
});
Here's the PHP that echos the variable as a button:
require "config.php"; // database connection
$in=$_GET['txt'];
if(!ctype_alnum($in)){ //
echo "Search By Name, or Entry ID";
exit;
}
$msg="";
$msg="";
if(strlen($in)>0 and strlen($in) <20 ){
$sql="select name, entry, displayid from item_template where name like '%$in%' LIMIT 10"; // the query
foreach ($dbo->query($sql) as $nt) {
//$msg.=$nt[name]."->$nt[id]<br>";
$msg .="<table style='table-layout:fixed;'> // Just the start of my table
<tr>
<td>Name</td>
<td>Entry ID</td>
<td>Display ID</td>
</tr>
<tr>
<td align=center><a href=http://wowhead.com/item=$nt[entry]>
$nt[name]</a>
</td>
<td>$nt[entry]</td>
<td>
<input type=button class=button value=$nt[displayid]> // The Value I need echoed out in a button is $nt[displayid]
</td>
</tr>
</table>"; // end of my table}
}
$msg .='';
echo $msg;
Not that it matters but here is the input text
<input type="text" id="theinput"/>
Make it easy on yourself and try to make your code easy to read. I personally prefer to write my html cleanly and outside of echo statements like so:
Html
if (strlen($in) > 0 and strlen($in) < 20) {
$sql = "select name, entry, displayid from item_template where name like '%{$in}%' LIMIT 10"; // the query
foreach ($dbo->query($sql) as $nt) {
//$msg.=$nt[name]."->$nt[id]<br>";
?>
<table style="table-layout:fixed;">
<tr>
<td>Name</td>
<td>Entry ID</td>
<td>Display ID</td>
</tr>
<tr>
<td align="center">
<?=$nt['name'];?>
</td>
<td><?=$nt['entry'];?></td>
<td>
<input type="button" class="button" value="<?=$nt['displayid'];?>">
</td>
</tr>
</table>
<?php
}
}
Javascript
$( document ).ready(function() {
var $theButtons = $(".button");
var $theinput = $("#theinput");
$theButtons.click(function() {
// $theinput is out of scope here unless you make it a global (remove 'var')
// Okay, not out of scope, but I feel it is confusing unless you're using this specific selector more than once or twice.
$("#theinput").val(jQuery(this).val());
});
});
Ok, here goes...
Use event delegation in your JavaScript to handle the button clicks. This will work for all present and future buttons
jQuery(function($) {
var $theInput = $('#theinput');
$(document).on('click', '.button', function() {
$theInput.val(this.value);
});
});
Less important but I have no idea why you're producing a complete table for each record. I'd structure it like this...
// snip
if (strlen($in)>0 and strlen($in) <20 ) :
// you really should be using a prepared statement
$sql="select name, entry, displayid from item_template where name like '%$in%' LIMIT 10";
?>
<table style="table-layout:fixed;">
<thead>
<tr>
<th>Name</th>
<th>Entry ID</th>
<th>Display ID</th>
</tr>
</thead>
<tbody>
<?php foreach ($dbo->query($sql) as $nt) : ?>
<tr>
<td align="center">
<?= htmlspecialchars($nt['name']) ?>
</td>
<td><?= htmlspecialchars($nt['entry']) ?></td>
<td>
<button type="button" class="button" value="<?= htmlspecialchars($nt['displayid']) ?>"><?= htmlspecialchars($nt['displayid']) ?></button>
</td>
</tr>
<?php endforeach ?>
</tbody>
</table>

In first table I am displaying values from database. But when user click on edit button below the table, Then that table values should be editable for user. I have succeeded in making editable fields but again when user click on submit then updated values are not displaying in first table. I know it's possible with jQuery or JavaScript. When I alert(newsales), the alert is undefined.
An easy way to handle this would be have two separate tables, and toggle between them when you edit a table. So for example we have a table that shows our normal data called shown and one with the input and select for a user to enter data called edit. These tables will share the same button, and when clicked it will toggle between the tables, making it look like it's switching between edit and show mode. This way we can just copy the values from the edit table to the text in the shown table. Here is an example:
$("#edit").hide(); // Hide the edit table first
$("#update").click(function() {
$("#edit").toggle();
$("#shown").toggle();
// If we are going from edit table to shown table
if($("#shown").is(":visible")) {
// Get the data from the edit table
var newSales = $("#edit tr:nth-child(1) td input[name='vouchertype']").val();
var newPay = $("#edit tr:nth-child(1) td select[name='mode']").val();
var newTax = $("#edit tr:nth-child(2) td select[name='tax']").val();
// Then add it to the shown table
$("#shown tr:nth-child(1) td:nth-child(2)").text(newSales);
$("#shown tr:nth-child(1) td:nth-child(3)").text(newPay);
$("#shown tr:nth-child(2) td:nth-child(1)").text(newTax);
$(this).val("Edit");
}
else $(this).val("Update");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table id="shown">
<tr>
<td>Sr no</td><td>Sales</td><td>Paid in</td>
</tr>
<tr><td>Taxed</td></tr>
</table>
<table id="edit">
<tr>
<td>Sr no</td><td><input type="text" name="vouchertype" value="Sales" /></td>
<td>
<select name="mode">
<option value="paidin">Paidin</option>
<option value="paidout">Paidout</option>
</select>
</td>
</tr>
<tr>
<td>
<select name="tax">
<option value="Taxed">Taxed</option>
<option value="Not Taxed">Not Taxed</option>
</select>
</td>
</tr>
</table>
<input id="update" type="submit" name="submit" value="Edit"/>
Notice: This is an answer to the original question, which is quite different then the new question added in as an edit.
I am having a problem on this because I always get the first value even if I click the last element of the table.
<table>
<?php
for($i=1;$i<=5;$i++){
?>
<tr>
<td><input type="text" id="testId" value="{$i}"><td>
<td><button class="testButton">Click Me</button></td>
</tr>
<?php
}
?>
</table>
for js file
$(document).ready(function(){
$( ".testButton" ).click(function(){
var a = document.getElementById("testId").value;
alert(a);
});
});
how can I get each value?
Don't forget that you actually need to echo $i on the value. And its also important to close the <td> markup properly.
<table>
<?php for($i=1;$i<=5;$i++){ ?>
<tr>
<td><input type="text" class="testClass" value="<?php echo $i; ?>"></td>
<td><button class="testButton">Click Me</button></td>
</tr>
<?php } ?>
</table>
Then on JS, just traverse the previous <td> to get the input values:
$(document).ready(function(){
$('.testButton').click(function(e){
var a = $(this).parent().prev('td').children('input.testClass').val();
alert(a);
});
});
Sample Output
you can assign id for only one element.
in this case, you may want to assign different ids like below.
<td><input type="text" id="testId{$i}"><td>
<td><button class="testButton" data-target="#testId{$id}">Click Me</button></td>
$(document).ready(function(){
$( ".testButton" ).click(function(){
var target = $(this).data("target");
var a = $(target).val();
alert(a);
});
});
