How can I pass id="'.$row["courseid"].'" into the ajax function,
I'm trying data:{'courseid':deleteId}, but is not working any ideas on how to fix this problem.
<?php
echo "<table width='100%'>";
echo "<tr>
<th>Course name</th>
<th>Delete</th>
<th>Edit</th>
</tr>";
?>
<?php foreach($rows as $row):
echo "<tr>";
echo '<td>' . htmlentities($row['coursename'], ENT_QUOTES, 'UTF-8') . '</td>';
echo '<td><button onclick="deleteC(' . $row['courseid'] . ')");"><font color="#e70404"> Delete </font> </button></td>';
echo '<td><a class="delete" id="'.$row["courseid"].'">Delette</a></td>';
echo "</tr> ";
endforeach;
echo "</table>";
?>
And this is the ajax function which is in the same page
<script type="text/javascript">
function deleteC(deleteId){
$.ajax({
type: "GET",
url: "deleteCourse.php",
data:{'courseid':deleteId},
success: function(result){
if(result=='correct'){
window.location='index.php';
}else {
window.location='coursesData.php';
}
}
});
}
</script>
This is the deleteCourse.php
<?php
require("connect.php");
if (isset($_GET['courseid']) && is_numeric($_GET['courseid']))
{
$id = $_GET['courseid'];
echo"$courseid";
$con=mysqli_connect("localhost","root","","independentstudyclass");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_query($con,"DELETE FROM courses WHERE courseid=$id");
echo "correct";
mysqli_close($con);
echo "correct";
}
else
{
header ("Location: ../index.php");
}
?>
Instead of this:
echo '<td><font color="#e70404"> Delete </font> </td>';
Just pass the id to the JS function as a parameter and use it:
PHP:
echo '<td><font color="#e70404"> Delete </font> </td>';
JS
function deleteC(deleteId){
$.ajax({
type: "GET",
url: "deleteCourse.php",
data:{'courseid':deleteId},
success: function(result){
if(result=='correct'){
window.location='index.php';
} else {
}
}
});
}

then here is my updateassigncourse.php

$result = mysql_query($sql);

If this is your exact code, then there is a missing ';'
$course = $course_codeapp
it should have been
$course = $course_codeapp;
I am working in a project where i want to show only those products to user which are selected by admin from database. Actualy i want to set the approval 1 or 0 in database when admin check or unchecked that checkbox.
jobs.php
$(document).ready(function(){
$('input.check').click(function(){
if($("input.check").is(':checked'))
{
$id = $(this).attr("id");
$.post("handle.php",{action:"checked",id:$id},function(data){
alert("Peoduct is set to display...");
});
}
else
{
alert("unchecked");
$id = $(this).attr("id");
$.post("handle.php",{action:"unchecked",id:$id},function(data){
alert("Peoduct is un-set to display...");
});
}
});
});
<?php
$dbqry = mysql_query("select * from job_category");
echo "<table width='50%', border='2'>
<tr>
<th>Catergory ID</th>
<th>Category Name</th>
<th>Remove</th>
<th>Update</th>
<th>Approval</th>
</tr>";
if($dbqry)
{
while($row = mysql_fetch_array($dbqry))
{
echo "<tr>";
echo "<td align='center'>" . $row['c_id'] . "</td>";
echo "<td align='center'>" . $row['cat_name'] ."</td>";
$cid = $row['c_id'];
$aprv = $row['approval'];
echo "<td align='center'><a href='remove.php?action=cat_remove&cid=$cid'>Remove</a></td>";
echo "<td align='center'>
<a href='Update-form.php?action=cat_update&cid=$cid'>Update</a></td>";
?>
<td align="center">
<input type='checkbox' name='approval' value='approval' id ="<? echo $cid; ?>" class="check"/>
</td>
</tr>
<?
}
echo "</table>";
echo '<br/>';
echo "<a href='add.php?action=cat_add'>Add New Category</a>";
}
else
{
die(mysql_error());
}
?>`
handle.php
`<?php
include 'include/connection.php';
$action = $_POST['action'];
$id = $_POST['id'];
//echo $action;
if($action == "checked")
{
$query = "update job_category set approval=1 where c_id=$id";
$result = mysql_query($query);
if(!$result)
{
echo die(mysql_error());
}
}
else if($action == "unchecked")
{
$query = "update job_category set approval=0 where c_id=$id";
$result = mysql_query($query);
if(!$result)
{
echo die(mysql_error());
}
}
?>`
Its working but when i refresh the page or seletc the URL and press enter then all the checked data appears unchecked even after that it does not change value of approval from 1 to 0 in database, but still it make me confuse about which items are checked or unchecked. Any suggestion will be appreciated.
modify checkbox line to show checked if approval=1 in database... try this
<input type='checkbox' name='approval' value='approval' <?php if($row["approval"]==1){ echo "checked=\"checked\"";}) ?> id ="<? echo $cid; ?>" class="check"/>
html
<input type='checkbox' name='approval' value='approval' <?php echo $row["approval"]?"checked=\"checked\"":'';?> id ="<? echo $cid; ?>" class="check"/>
then add js
$(function(){
$('input[type=checkbox]').each(function(){
if($(this).attr('checked') && $(this).attr('checked')=='checked'){
$(this).attr('checked', true);
}else{
$(this).attr('checked', false);
}
})
})
and
if($("input.check").is(':checked'))
to
if($(this).is(':checked'))
