I am trying to print the elements of an array in PHP which was passed from Javascript. I think the js array is being passed but for some reason it is not being printed via php. Sorry if my code is not properly indented. TIA
<?php
$link = mysqli_connect("localhost","xxxx", "xxxxxx","xxxx");
if($_POST['delete']){
$delete= json_decode($_POST['str'], true);
foreach($delete as $x){
echo"<script> alert(".$x.");</script>";
}
}
?>
<html lang="en">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</head>
<body >
//This is a table which displays rows from a database.
//The user selects rows and the ids of those rows are
//are stored in a javascript array called 'toDelete'
//I want to pass this array to PHP
<form method="post" id="myForm" >
<table id="secondDiv" >
<tr>
<th >
<form><input class="checkbox"type="checkbox" name="selectAll" id="selecctall" value=""></form>
</th>
<th>Date</th>
<th>Event</th>
<th>Details</th>
<th>Time & Location</th>
</tr>
<?php
$link = mysqli_connect("localhost","xxxx", "xxxxxx","xxxx");
$query = "SELECT * FROM meetings";
if($result = mysqli_query($link,$query)){
while($row = mysqli_fetch_array($result)){
echo "<tr>";
echo "<td><form ><input class=\"checkbox1\" type=\"checkbox\" name=\"".$row['meetingNo']."\" >
</form></td>";
echo "<td>".$row['date']."</td>";
echo "<td>".$row['event']."</td>";
echo "<td>".$row['details']."</td>";
echo "<td>".$row['location']."</td>";
echo "</tr>";
}
}
?>
</table>
<!-- <input type="submit" class="btn btn-warning" value="Edit" /> -->
<input type="hidden" id="str" name="str" value="" />
<input type="submit" id="btn" name="delete" value="Delete" />
</form>
<script>
var toDelete = new Array();
$(document).ready(function() {
$('#selecctall').click(function(event) { //on click
if(this.checked) { // check select status
$('.checkbox1').each(function() { //loop through each checkbox
this.checked = true; //select all checkboxes with class "checkbox1"
});
}else{
$('.checkbox1').each(function() { //loop through each checkbox
this.checked = false; //deselect all checkboxes with class "checkbox1"
});
}
});
});
// JSON.stringify(toDelete);
$('input:checkbox').change(
function(){
if ($(this).is(':checked')) {
toDelete.push(this.name);
}
return true;
}
);
$(document).ready(function(){
$("#btn").click( function() {
$.post( $("#myForm").attr("action"),
$('#str').val(JSON.stringify(toDelete))
);
});
$("#myForm").submit( function() {
return false;
});
});
</script>
</body>
</html>
