I'm stuck with trying to process multiple mySQL updates at the same time. I have 4 select/optiion boxes that pull entries from a db table. I want to be able to update the db onChange using JQuery. I have managed to get this working with one select module but as soon as I add more it spins out. I know that the main bad code is in db_submit.php but really not sure how else to write it. I know there has to be a cleaner way to do this.
FORM PAGE- INPUT.PHP
<html>
<head>
<script src="../assets/scripts/jquery-2.0.3.min.js"></script>
<script>
function updateDb() {
$.post("db_submit.php", $("#console").serialize());
}
</script>
<?php
include 'db_connect.php';
?>
</head>
<body>
<form id="console">
<select id="frame1" name="frame1" onChange="updateDb()">
<option value="">Select Channel</option>
<?php
$result = mysqli_query($con,"SELECT * FROM feedContent");
while ($row = mysqli_fetch_array($result)) {
echo "<option value='" . $row['url'] . "'>" . $row['name'] . "</option>";
}
?>
</select>
<select id="frame2" name="frame2" onChange="updateDb()">
<option value="">Select Channel</option>
<?php
$result = mysqli_query($con,"SELECT * FROM feedContent");
while ($row = mysqli_fetch_array($result)) {
echo "<option value='" . $row['url'] . "'>" . $row['name'] . "</option>";
}
?>
</select>
<select id="frame3" name="frame3" onChange="updateDb()">
<option value="">Select Channel</option>
<?php
$result = mysqli_query($con,"SELECT * FROM feedContent");
while ($row = mysqli_fetch_array($result)) {
echo "<option value='" . $row['url'] . "'>" . $row['name'] . "</option>";
}
?>
</select>
<select id="frame4" name="frame4" onChange="updateDb()">
<option value="">Select Channel</option>
<?php
$result = mysqli_query($con,"SELECT * FROM feedContent");
while ($row = mysqli_fetch_array($result)) {
echo "<option value='" . $row['url'] . "'>" . $row['name'] . "</option>";
}
?>
</select>
</form>
</body>
<?php
mysqli_close($con);
?>
</html>
PROCESSING PAGE- DB_SUBMIT.PHP
<?php
include 'db_connect.php';
$frame1= mysqli_escape_String($con,$_POST['frame1']);
$frame2= mysqli_escape_String($con,$_POST['frame2']);
$frame3= mysqli_escape_String($con,$_POST['frame3']);
$frame4= mysqli_escape_String($con,$_POST['frame4']);
$query = "UPDATE frameContent SET url='".$frame1."' WHERE name='frame1'";
$query = "UPDATE frameContent SET url='".$frame2."' WHERE name='frame2'";
$query = "UPDATE frameContent SET url='".$frame3."' WHERE name='frame3'";
$query = "UPDATE frameContent SET url='".$frame4."' WHERE name='frame4'";
mysqli_query($con,$query);
mysqli_close($con);
?>
I know that constantly setting the $query variable is causing problems but I'm not sure how else I can do this in the one page. Any help would be much appreciated.
Thanks!
