How to send MySQL id within PHP loop to AJAX PHP script
Question
I am battling with how to isolate specific MySQL id's when clicked for AJAX call to PHP counter file. Originally I used non-javascript HTLM with echoed PHP to create an array of blocks, each representing a single media file, on a page. When user clicks on block then it goes to a PHP counter file and plays the media file. It is working fine. Running into problems when trying to convert to AJAX/javascript running of the PHP counter file.
The problems appear to be:
- the proper ID is not registered using the onclick.
- the ID is not being passed to the Ajax called php file and the counters are not updating.
The javascript in head of main block building file is:
<script type="text/javascript" src="jquery.js"></script>';
Hundreds of blocks, each with separate MySQL ID are built and displayed on main page.
ADDITION 040913: The PHP starts with:
WHILE ($varX <= $varY) {
mysql_select_db($database_cms_test, $cms_test);
$query = "SELECT * FROM reference WHERE rank=$varRank";
$result = mysql_query($query) or die();
$row = mysql_fetch_array($result); ...
The Ajax part starts here:
<script type="text/javascript">
function runCounter() {
var currentID = 222;
$.get("counter5.php?id=222");
alert("the current id is " + 222);
}
</script>
<a title="Media File Name" href "#" onclick= "runCounter();" id="sprytrigger1">
The equivalent Ajax code prior to echoing is:
echo '<script type="text/javascript">';
echo 'function runCounter() {';
echo ' var currentID = ';
printf ("%s", $row['id']);
echo '; $.get("';
echo 'counter5.php?id=';
printf ("%s", $row['id']);
echo '"); alert("the current id is " + ';
printf ("%s", $row['id']);
echo ');} </script>';
echo '<a title="';
printf ("%s", $row['song_name']);
echo '" href "#';
echo '" onclick= "runCounter();';
echo '" id="sprytrigger';
echo $varRank;
echo '">';
In the counter5.php file, the main id request code is:
$id = mysql_real_escape_string($_GET['id']);
Thank you so much in advance for your advice / suggestions.

Can you try this code...
$scr = 'var currentID = ' . $row['id'] .
'$.get("counter5.php?id='. $row['id'] .'")' .
'alert("the current id is " + '. $row['id'] .')';
script
<script type="text/javascript">
$(document).on('click', '#btn-id', function(){
runCounter();
})
function runCounter(){
<?php echo $scr; ?>
}
</script>
Full code
<html>
<title>Your title</title>
<head>
<?php
// get the value/content of $row variable here...
$scr = 'var currentID = ' . $row['id'] .
'$.get("counter5.php?id='. $row['id'] .'")' .
'alert("the current id is " + '. $row['id'] .')';
?>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">
$(document).on('click', '#sprytrigger1', function(){
runCounter();
})
function runCounter(){
<?php echo $scr; ?>
}
</script>
</head>
<body>
<! -- your body here -->
<a href="#" id="sprytrigger1">Click me!</a>
</body>
</html>
I hope this will help you in some way.

为什么使用echo，如果您可以直接退出php并再次进入
?>your code here<?php
