I have been trying for two weeks to add a collapsible button which should reveal the edit-form. I found something, but that java code didn't work properly inside my PHP code . For example, it works two by two and it is very annoying.
I tried to add another variables which could change that issue, but didn't work. After that, worked three by three.
<?php
if(isset($_SESSION['id'])) {
if($_SESSION['id'] == $row2['id']){
echo "<button type='submit' class='edit-comment'>Edit</button>
<div class='content'><form class='content edit-form' method='POST' action='".editComments($conn)."'>
<input type='hidden' name='comment_id' value='".$row['comment_id']."'>
<input type='hidden' name='user_id' value='".$row['user_id']."'>
<input type='hidden' name='date' value='".date('d-m-Y H:i:s')."'>
<textarea class='comment' name='comment'>".$row['comment']."</textarea><br>
<button id='edit' name='submite' type='submit'>Edit</button>
</form></div>
<script>
var coll = document.getElementsByClassName('edit-comment');
var i;
for (i = 0; i < coll.length; i++) {
coll[i].addEventListener('click', function() {
this.classList.toggle('active');
var content = this.nextElementSibling;
if (content.style.maxHeight){
content.style.maxHeight = null;
} else {
content.style.maxHeight = content.scrollHeight + 'px';
}
});
}
</script>"; ?>
I expect to reveal all the comments, but works just two by two. Here is a picture to understand better what I said:
I don't know if the following will be of interest as it's likely I have perhaps misunderstood the problem having not been able to view all the code at this point. The following will create ( emulate the creation of ) several of these minimised/hidden forms and a single javascript listener is registed for all of them
