Having an issue. I need to remove the associated element on the click of a button from a list of results provided by a MySQL query. Only the first image is being hidden on the click of the remove button. The rest of the images returned do nothing.
Here is my code :
PHP:
<?php
while ($image_row = mysqli_fetch_array($image_result)) { ?>
<span class="listing_image_preview" id="image_<?php echo $image_row['id']; ?>">
<img src="<?php echo $image_row['image_thumb']; ?>" style="border:6px solid #EEE; margin:6px;" />
<button id="remove_image" class="btn btn-default btn-xs" imageId="<?php echo $image_row['id']; ?>">Remove</button>
</span>
<?php
}
?>
jQuery:
$(document).ready(function() {
$("#remove_image").click(function() {
var image_id = $(this).attr('imageId');
$('#image_'+image_id).hide();
})
});
All your buttons have the same id:
<button id="remove_image"
And your jquery script will only find one element with the following selector:
$("#remove_image")
Here's one way to solve it:
Add remove_on_click to the button's class (I also made the id's unique)
<?php
while ($image_row = mysqli_fetch_array($image_result)) { ?>
<span class="listing_image_preview" id="image_<?php echo $image_row['id']; ?>">
<img src="<?php echo $image_row['image_thumb']; ?>" style="border:6px solid #EEE; margin:6px;" />
<button id="remove_image_<?php echo $image_row['id']; ?>" class="btn btn-default btn-xs remove_on_click" imageId="<?php echo $image_row['id']; ?>">Remove</button>
</span>
<?php
}
?>
In your jquery script select on class remove_on_click:
$(document).ready(function() {
$(".remove_on_click").click(function() {
var image_id = $(this).attr('imageId');
$('#image_'+image_id).hide();
})
});

hi guys i am trying to get a button id that is in a for loop so whenever the button click the unique id that can be differentiated from other ids should be able to work. let me show you my code.
<?php foreach ($message as $key ) : ?>
<?php echo $senders_user_id=$key['senders_id']; ?>
<div class="senders_id" S_id="<?php echo $key['senders_id']; ?>" style="display: none;"></div>
<a class="list-group-item">
<div class="checkbox">
<label>
<?php echo form_open(,['id'=>'sender_user_id']); ?>
<input type="checkbox">
<button id="senders_id" class="Read" S_id="<?php echo $key['senders_id'];?>" onclick="readbyuser($senders_user_id);">Read</button>
<button id="senders_id" class="unread" S_id="<?php echo $key['senders_id'];?>" onclick="unreadbyuser($senders_user_id);">Unread</button>
</label>
</div>
<span class="glyphicon glyphicon-star-empty"></span><span class="name" style="min-width: 120px;
display: inline-block;"><?php echo $key['uname']; ?></span> <span class=""><?php echo $key['textdata']; ?></span>
<span class="text-muted" style="font-size: 11px;"></span> <span class="badge">12:10 AM</span> <span class="pull-right"><span class="glyphicon glyphicon-paperclip">
<?php echo form_close(); ?>
</span></span></a>
<?php endforeach; ?>
</div>
Now here there are three post meaning three 'senders_id' so when i click on button Read the id of that should pass but the same id is passing again and again no matter which button i click on
Here is my code
function readbyuser()
{
var senders_id=$('#senders_id').attr('S_id');
var Recievers_id=$('.Recievers_id').attr('R_id');
jQuery.ajax({
type:'post',
url:'<?php echo base_url("user/read_by_user"); ?>',
data:{id:senders_id,R_id:Recievers_id},
dataType:'json',
success:function(data)
{
console.log(data);
alert(data);
$('.unread').removeClass('unread_user');
$('.Read').addClass('read_user');
}
});
}
function unreadbyuser()
{
var senders_id=$('#senders_id').attr('S_id');
var Recievers_id=$('.Recievers_id').attr('R_id');
jQuery.ajax({
type:'post',
url:'<?php echo base_url("user/unread_by_user"); ?>',
data:{id:senders_id,R_id:Recievers_id},
dataType:'json',
success:function(data)
{
$('.Read').removeClass('read_user');
$('.unread').addClass('unread_user');
}
});
}
please tell me what i am doing wrong
<button id="senders_id" class="Read" S_id="<?php echo $key['senders_id'];?>" onclick="readbyuser($senders_user_id);">Read</button>
<button id="senders_id" class="unread" S_id="<?php echo $key['senders_id'];?>" onclick="unreadbyuser($senders_user_id);">Unread</button>
Two elements cannot have samei id. Use class name instead.
Also you can pass PHP values directly in this.
onclick="readbyuser($senders_user_id);"
as
onclick="readbyuser(<?php echo $key['senders_id'];?>);"
slightly varied question but I have a script that runs and gets data from a mysql db. The end result shows them as buttons, when i click the buttons it gives me an alert with the correct id number correspsonding to whats selected, but when i try to put that into a textfield is isnt the same, its basically the last in the mysql? WHy would the alert show the correct and the updated textfield so totally different information??
The working php that alerts the correct info is :
<?php
include('config.php');
$action = $_REQUEST['action'];
if($action=="showAll"){
$stmt=$dbcon->prepare('SELECT product_id, product_name FROM products ORDER BY product_name');
$stmt->execute();
}else{
$stmt=$dbcon->prepare('SELECT product_id, product_name FROM products WHERE cat_id=:cid ORDER BY product_name');
$stmt->execute(array(':cid'=>$action));
}
?>
<div class="row">
<?php
if($stmt->rowCount() > 0){
while($row=$stmt->fetch(PDO::FETCH_ASSOC))
{
extract($row);
?>
<div class="col-xs-3">
<div style="border-radius:3px; border:#cdcdcd solid 1px; padding:22px;"><button type="button" class="btn btn-default" onclick="alert('<? echo $product_id; ?>')"><?php echo $product_name; ?></button></div><br />
</div>
<?php
}
}else{
?>
<div class="col-xs-3">
<div style="border-radius:3px; border:#cdcdcd solid 1px; padding:22px;"><button type="button" class="btn btn-default" onclick="alert('<? echo $product_id; ?>')"><?php echo $product_name; ?></button></div><br />
</div>
<?php
}
?>
</div>
<div>
text : <input id="textField1" type="text" value="0" align="right" size="13"/><br>
</div>
<script>
function display()
{
document.getElementById("textField1").value = "<? echo $product_name; ?>";
}
</script>
But if change the button to use the 'display script' it just shows last in database?
HTML + PHP
<?php
for($i=0;$i<5;$i++){
?>
<input readonly class="copyTarget" id="copyTarget<?php echo $i; ?>" value="val<?php echo $i; ?>">
<span>
val<?php echo $i; ?>
</span>
<button class="btn btn-primary" id="copyButton<?php echo $i; ?>" onClick="reply_click(this.id, $('.copyTarget').attr('id'));">Copy</button>
<?php
}
?>
JS
<script>
function reply_click(clicked_id, target_id) {
alert(clicked_id);
alert(target_id);
}
</script>
What i want
I want to get the both values for copyTarget and copyButton as per loop cycle. It means
If current value of $i = 3
then I want alert values like,
clicked_id = copyTarget3
target_id = copyButton3
What i am currently getting is,
If current value of
$i = 3
then I want alert values like,
clicked_id = copyTarget0
target_id = copyButton3
Its taking first value of ID(copyTarget) stored initially. I want current loop cycle value.
Any help would do
Thanks
Why use JS in handler?
Try:
onClick="reply_click('copyButton<?php echo $i; ?>', 'copyTarget<?php echo $i; ?>')"
Also you should store id names (copyButton and copyTarget) in php variable, so you can change them in one place.
You could try something like below. However, I would go by Maxx's answer .. It really depends on what you plan to do with the rest of code etc.
<?php
for($i=0;$i<5;$i++){
?>
<div>
<input readonly class="copyTarget" id="copyTarget<?php echo $i; ?>" value="val<?php echo $i; ?>">
<span>
val<?php echo $i; ?>
</span>
<button class="btn btn-primary" id="copyButton<?php echo $i; ?>" onClick="reply_click(this)">Copy</button>
</div>
<?php
}
?>
<script>
function reply_click(btn) {
var clicked_id = $(btn).attr('id');
var target_id=$(btn).parent().find('span').html();
alert(clicked_id);
alert(target_id);
}
</script>
Try This
<?php
for($i=0;$i<5;$i++){
?>
<input readonly class="copyTarget" id="copyTarget<?php echo $i; ?>" value="val<?php echo $i; ?>">
<span>
val<?php echo $i; ?>
</span>
<button class="btn btn-primary" id="copyButton<?php echo $i; ?>" onClick="reply_click(this.id);">Copy</button>
<?php
}
?>
JS
<script>
function reply_click(clicked_id) {
alert(clicked_id); //clicked id
alert(clicked_id.split('copyButton').join('copyTarget')); // target id
}
</script>
I've a such PHP-script:
<?php
$menuItemList = getSubPkgCategForDDList(echo "<script>showSubCatForMenuItem();</script>");
if(isset($menuItemList)){
foreach($menuItemList as $u){
?>
<p><span contenteditable="true"><?php echo $u->name ?></span><button type="button" class="btn btn-danger btn-xs" onclick="deleteCategory(<?php echo $u->pkg_cat_ddlist_id ?>)">Delete</button>
<button type="button" class="btn btn-success btn-xs" onclick="editCategory(<?php echo $u->pkg_cat_ddlist_id ?>,<?php echo "'".$u->name."'" ?>)">Save</button></p>
<?php
}
}
?>
Function getSubPkgCategForDDList must generate html-code,so it depends from parameter, which is send to this function.
I get this parameter from such js-function showSubCatForMenuItem():
function showSubCatForMenuItem(){
console.log($('#menuItem').val());
return $('#menuItem').val();
}
This function takes data from such dropdown list:
<select id="menuItem" onchange="showSubCatForMenuItem()">
<?php
$itemList = getPackCategoriesForAsideMenu();
if(isset($itemList)){
foreach($itemList as $u){
?>
<option value="<?php echo $u->pkg_cat_ddlist_id ?>"><?php echo $u->name ?></option>
<?php
}
}
?>
</select>
How to do that parameter transfer is correctly, when I load page and select item from dropdown list? Sorry for my English.
You should take advantage of $_SESSION in this case. Now print out the drop down :
<select id="menuItem">
<?php
$itemList = getPackCategoriesForAsideMenu();
if(isset($itemList)){
foreach($itemList as $u){
echo'<option value="'.$u->pkg_cat_ddlist_id.'">'.$u->name.'</option>';
}
}
?>
</select>
Write the JS script :
$("#menuItem").live('change',function(){
var val = $(this).val();
$.post('change.php',{data:val},function(){
// Do some
});
});
And create a php file named change.php :
<?php
session_start();
if(!empty($_POST['data'])){
$_SESSION['menu_sltd'] = (int) $_POST['data']; // It makes sure that the data sent is integer / number
}
?>
Now, change your main script to :
<?php
session_start();
$menu_sltd = (!empty($_SESSION['menu_sltd']) ? $_SESSION['menu_sltd'] : 'default id'); // Default id is the default menu id if it's blank
$menuItemList = getSubPkgCategForDDList($_SESSION['menu_sltd']);
if(isset($menuItemList)){
foreach($menuItemList as $u){
echo'
<p>
<span contenteditable="true">'.$u->name.'</span>
<button type="button" class="btn btn-danger btn-xs" onclick="deleteCategory('.$u->pkg_cat_ddlist_id.')">Delete</button>
<button type="button" class="btn btn-success btn-xs" onclick="editCategory('.$u->pkg_cat_ddlist_id.',\''.$u->name.'\')">Save</button>
</p>';
}
}
?>
GOOD LUCK,, glad to help you. Don't give up
In javascript function showSubCatForMenuItem() you can set the value of selected item in some hidden field on every change event the value selected by user will get updated, then while saving the use this value that is saved in the hidden field.
i need to get the name and value from li element and display it after selection as the button value, what i need more is for that single value to be stored in a php var for latter submit, i got this far but now i am stuck and keep getting 1 size only
CODE
<button id="changename" class="btn dropdown-toggle size-selector-btn" type="button" data-toggle="dropdown">Select your size <span class="caret" style="display: none;"></span>
</button>
<ul class="dropdown-menu size-list" role="menu">
$productAttributeOptions = $product->getTypeInstance(true)->getConfigurableAttributesAsArray($product);
$attributeOptions = array();
foreach ($productAttributeOptions as $productAttribute) {
foreach ($productAttribute['values'] as $attribute) {
$attributeOptions[$productAttribute['label']][$attribute['value_index']] = $attribute['store_label'];
}
}
$key = "Size";
foreach($attributeOptions[$key] as $size){ ?>
<li id="<?php echo $size; ?>" onclick="changeName()"><?php echo $size; ?></li>
<?php }
} ?>
</ul>
</div>
<script>
function changeName() {
document.getElementById("changename").innerHTML = "<?php echo $size; ?>";
}
</script>
OK, well there are 2 issues i can see. 1st that your third foreach loop looks like it should be nested within the others, but its not.
The second issue is that that you are missunderstanding how php and js work. Php is ran on the server before the page is rendered, so the value of $size in your js function will be whatever the LAST value of was.
To fix this, 1st nest the foreach correctly (when using php inline with html, i find its best to use the template syntax for blocks - eg if: endif;, foreach: endforeach; to aid readability), then adjust your js function to take a parameter, and pass that parameter in the onclick event by grabing the clicked elements id:
<button id="changename" class="btn dropdown-toggle size-selector-btn" type="button" data-toggle="dropdown">Select your size <span class="caret" style="display: none;"></span>
</button>
<ul class="dropdown-menu size-list" role="menu">
<?php
$productAttributeOptions = $product->getTypeInstance(true)->getConfigurableAttributesAsArray($product);
$attributeOptions = array();
foreach ($productAttributeOptions as $productAttribute) :
foreach ($productAttribute['values'] as $attribute) :
$attributeOptions[$productAttribute['label']][$attribute['value_index']] = $attribute['store_label'];
$key = "Size";
foreach($attributeOptions[$key] as $size):?>
<li id="<?php echo $size; ?>" onclick="changeName(this.id);"><?php echo $size; ?></li>
<?php endforeach;
endforeach;
endforeach;
?>
</ul>
</div>
<script>
function changeName(size) {
document.getElementById("changename").innerHTML = size;
}
</script>
