jsfiddle
I'm trying to print the input text field values on nextpage (postdata.php). But it always print the first row result only. I didn't get the remaining row values on next page. I've posted my full codes on jsfiddle.. How do i get the remaining js dynamic row values in php (postdata.php page)?
JS
$(document).ready(function(){
$("span").click(function(){
$("#container").append('<tr><td>Email : </td><td><input type="text" name="email[]" placeholder="Email id" /></td> <td>Name : </td><td><input type="text" name="name[]" placeholder="Your Name "/></td> <td><a title="Delete this row" href="javascript:void(0);" class="remove">Del</a></td></tr>');
});
$("#container").on('click','.remove',function(){
$(this).parent().parent().remove();
});
});
Php
<?php
echo "
<table>
<tr>
<td>
Email :
</td>
<td>
$_POST[email]
</td>
<td>
Name :
</td>
<td>
$_POST[name]
</td>
</tr>
</table>";
?>
Since name of fields you declared is array the $_POST becomes multidimensional array.So try like this
<?php
$size = sizeof($_POST['email']);
echo "<table>" ;
for($i=0; $i<$size;$i++)
{
echo "
<tr>
<td>
Email :
</td>
<td>
".$_POST['email'][$i]."
</td>
<td>
Name :
</td>
<td>
".$_POST['name'][$i]."
</td>
</tr>
";
}
echo "</table>";
?>
also in your html change names of Name and Email field to name[] and email[] respectively.Also you have misplaced the form tag. It starts after <table> and ends after <table>. which was not correct. so place form tag before table tag
When you add square brackets to the name of an input field, PHP will receive it's value as an array. Your JS code is fine, but the PHP code doesn't handle arrays at all. Look at the following:
echo "
<table>";
if(!is_array($_POST['email'])) {
$_POST['email'] = array($_POST['email']);
$_POST['name'] = array($_POST['name']);
}
foreach($_POST['email'] as $key => $email) {
// get the corresponding name to the email
$name = $_POST['name'][$key];
echo "<tr>
<td>
Email :
</td>
<td>
$email
</td>
<td>
Name :
</td>
<td>
$name
</td>
</tr>";
}
echo "</table>";
Note: This code will check whether multiple values were submitted or not and will work in both scenarios.

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>
<?php endif;
I need a if loop in view file and a javascript when profile id is entered it should show all the related elements in the form and i'm doing this in codeignitor and this is the part of view file
<tr>
<td width='50%'>
<table width="50%"><tr>
<td width="50%"><strong>Profile ID </strong></td>
<td width="50%"><input type="text" id="profile_id" name="profile_id" value="<?php echo $reg_personal_details->profile_id;?>"placeholder="Employee ID "/><?php echo form_error('profile_id');?><br></td>
</tr>

<input type="text" id="profile_type" name="profile_type" value="<?php echo $reg_personal_details->profile_type;?>"placeholder="Employee Type"/><?php echo form_error('profile_type');?><br>
</td>
</tr>
<tr>
here is my table:
profile
(profile_id,
profile_fname,
profile_lname,
profile_email,
profile_mobile,
profile_type,
profile_gender,
profile_dob,
profile_marital_status,
profile_religion,
profile_blood_group,
profile_nationality,
profile_iris,
profile_biometric,
profile_department,
profile_designation,
profile_project_designation,
profile_image,
address_1,
address_2)
profile_id is a foreign key and its primary key is in other table as emp_acc_id
model for the above is :
public function reg_personal_details()
{
$reg_personal_details = array(
// i also need a condition here to read the entered profile_id all that below data must be store in that id only//
'profile_type' => $this->input->post('profile_type'),
'profile_gender' => $this->input->post('profile_gender'),
'profile_dob' => $this->input->post('profile_dob'),
'profile_marital_status' => $this->input->post('profile_marital_status'),
'profile_religion' => $this->input->post('profile_religion'),
'profile_blood_group' => $this->input->post('profile_blood_group'),

'profile_iris' => $this->input->post('profile_iris'),
'profile_biometric' => $this->input->post('profile_biometric'),
'profile_department' => $this->input->post('profile_department'),
'profile_designation' => $this->input->post('profile_designation'),
'profile_project_designation' => $this->input->post('profile_project_designation'),
);
$this->db->update('profile',$reg_personal_details);
You Should write a java Script which would check if a particular element exists or not i.e if its value is not null then generate a new row tags dynamically and set its value what we get in response of the query.
For generating a tag dynamically you can refer the following page:-
http://www.dustindiaz.com/add-and-remove-html-elements-dynamically-with-javascript/
we have a function to check whether data is present or not i.e., empty()and we just need to use it in if loop like this "if (!empty($var name))" and can also use "if(empty($var name)) " so if there is no data then it doesn't show any error and if data is present in db it shows that data
<tr>
<td width='50%'>
<table width="50%"><tr>
<td width="50%"><strong>Profile ID </strong></td>
<td width="50%"><input type="text" id="profile_id" name="profile_id" value="<?php
if (!empty($reg_personal_details)) {
echo $reg_personal_details->profile_id;
} else
echo $profile_id;
?>"placeholder="Employee ID "/><?php echo form_error('profile_id'); ?><br></td>
</tr>
<?php //if($reg_personal_details!=array()){ ?>
<td><strong>Employee Name </strong></td>
<td>
<input type="text" id="profile_fname" name="profile_fname" value="<?php
if (!empty($reg_personal_details)) {
echo $reg_personal_details->profile_fname;
}
?>" placeholder="Employee Name"/><?php echo form_error('profile_fname'); ?><br>
</td>
</tr>
<tr>
<td><strong>Employee Type </strong></td>

I am getting data from the database:
<table>
<?php
$select_data = mysql_query(" select * from `data_table` ") or die(mysql_error());
while($data_row = mysql_fetch_array($select_data))
{
?>
<tr>
<td>
<img src="../Stuff-site_data_images/<?php echo$data_row['data_image_name']?>" width="100" height="100" />
</td>
<td> <?php echo $data_row['data_image_name'];?> </td>
<td> <?php echo $data_row['data_description'];?> </td>
I want to get data from here:
<td align="center" class="row_id">
<input class="inner_row_id" type="hidden" value="<?php echo $data_row['data_id'];?>" name="show_detail_button" id="show_detail_button"> Show All
</td>
I want to get data from here:
</tr>
<?php
}
?>
</table>
so as far as I know jQuery will conflict when there is more than 1 id so that's why I used CSS class names "row_id" & "inner_row_id".
When I click on "row_id" I want the value of "inner_row_id"
and for that I have written the code below:
$(".row_id").click(function(e){
var row_id = $(".inner_row_id").val();
alert("Le click thyuu....");
});
Is there any one who suggest me what to do in this...
This should work
$(".row_id").click(function(e){
alert($(this).find('.inner_row_id').val());
})
The "click" function gives you access to this, which is the element that you clicked on. Find then looks for any decedents of the element which have class .inner_row_id.
Link to jsFiddle
As I see you are creating the input dynamically so use below JS:
$(".row_id").on('click',function(e){
var row_id = $(this).children('.inner_row_id').val();
alert("Le click thyuu....");
});
DEMO.
In my code,when any text is entered into the textbox and click on add attribute button, entered value displayed on page for two times, one in first row of table and another one is in first row of second table. Now question is, when i entered text into another textbox which is in second row of second table, it should display the entered text.but it can't display. it is not working.
<script>
var i = 0;
document.getElementById('add-val').innerHTML='';
function insRow()
{
i++;
var x=document.getElementById('myTable').insertRow(-1)
var a=x.insertCell(-1)
var txt=document.getElementById('add-val').value;
a.innerHTML=txt;
// for <tr> of table
var row = document.getElementById("myRow");
var newrow=document.getElementById("myRow1");
var x = row.insertCell(-1);
var y = newrow.insertCell(-1);
x.innerHTML=txt; //+ '<br>' +
y.innerHTML='<input type="text" name="nm" />';
}
document.getElementById('add-val').innerHTML='';
</script>
& this is html code.
<form method="post" name="form">
<input type="text" name="attr" id="add-val"> <input type="button" onClick="insRow()" value="Add Attribute">
<table width="27" height="17" id="myTable"> </table>
<table cellpadding="13px">
<tr id="myRow"> </tr>
<tr id="myRow1"> </tr>
</table>
<input type="submit" value="Add option" onClick="insRow()"/>
<?php
if(isset($_POST['submit']))
{
$val= $_POST['add'];
echo $val;
}
?>
</form>
It should be
y.innerHTML='<input type="text" name="nm[]" />';
The []'s after nm
name="nm[]"
Serve to store all new generated fields into an array, which can then be accessed by $_POST
Which you then just access like so....
$val = $_POST['nm'];
foreach($val as $v){
echo $v; // display what user entered
}
// var_dump($val) will show you all the users seperate input for each field
HTML Code :
<form method="post" name="form">
<input type="text" name="attr" id="add-val"> <input type="button" onClick="insRow()" value="Add Attribute">
<table width="27" height="17" id="myTable"> </table>
<table cellpadding="13px">
<tr id="myRow"> </tr>
<tr id="myRow1"> </tr>
</table>
<input type="submit" value="Add option" onClick="insRow()"/>
<?php
if(isset($_POST['submit']))
{
$val= $_POST['nm'];
echo $val;
}
?>
</form>
put the name of input whos value you want to print in place of attr
$val= $_POST['attr'];
I'm caught in a set of twisting codes. I've a table in a form which consists of all the information from one table say emp_info. I am not including all the mysql query and db connection but just suppose this table has fetched information from emp_info table from my database. Example:
<table align="center">
<form name="f1" action="update.php" method="post">
<tr>
<td>Enter name : </td><td><input type="text" name="ename" id="field1"
disabled="disabled" /></td><td><input id="myCheckBox1" type="checkbox"
onclick="enableText1(this.checked, 'field1');" />
</td>
</tr>
<tr>
<td>Enter Address : </td><td><input type="text" name="address" id="field2"
disabled="disabled" /></td><td><input id="myCheckBox2" type="checkbox"
onclick="enableText2(this.checked, 'field2');" /></td>
</tr>
<tr>
<td><input type=""submit value="submit"/></td>
</tr>
</form>
</table>
and following is the respective JAVASCRIPT written in the HEAD section:
<script type="text/javascript">
function enableText1(checkBool, textID)
{
text1 = document.getElementById(textID);
//Disable the text field
text1.disabled = !checkBool;
//Clear value in the text field
if (!checkBool) { text1.value = ''; }
}
function enableText2(checkBool, textID)
{
text2 = document.getElementById(textID);
//Disable the text field
text2.disabled = !checkBool;
//Clear value in the text field
if (!checkBool) { text2.value = ''; }
}
</script>
I want user to check the checkbox to enable the textbox to edit it. What can a user do with it? He can check the checkbox to edit it and when he unchecks it once again textbox will be disabled. That means, what he edited in the checkbox is going to be locked. To prevent him from doing it; I'm setting the textbox to empty; once he unchecks the checkbox. It's working up to it. My real problem starts from here. when the textbox is disabled and he submits the records to update, it throws an error while accepting the value using POST method ($name=$_POST['name']) in update.php:
Notice: Undefined variable: address in C:\xampp\htdocs\xampp\Test\HRMS\try\chcking with checkboxes\update.php on line 4
My main intention is to update the record into the temporary table. When a record is submitted using disabled textbox or empty textbox; in that case I would like to fetch its value from the old table and store it into the temporary table. I do not know how clear I am but accepting some support from enthusiastic master's in coding here. Thanks in advance.
please check my actual code. I am including both the pages below :
<?php
session_start();
if(!$_SESSION['logged'])
{

exit;
}

//echo 'Welcome, '.$_SESSION['email'];

When a field is marked "disabled" it doesn't get submitted to the server, so the value is lost. You either need to adapt your server side code to be aware of the possibility that the textbox is unset, or use readonly="readonly" instead of disabled="disabled" to make the text field uneditable. Read only controls are still submitted to the server, they just can't be edited by the user.
