Ajax POST is sending empty parameters

Question

UPDATE - I've solved the problem

I found the problem, it was the property of the post_max_size in php.ini which was set to 8MB. After changing it to 20MB everything worked as it should. Thanks for pointing out some syntax problems in the code.

Original post

I have this code in the body tag of a page:

<script type = "text/javascript" >
    $(document).ready(function() {
        var scriptPath = "<?php echo $jobJSPath[0]; ?>";
        if (scriptPath != "") {

            var hasInput = "<?php echo $hasInput; ?>";
            var jobExecIp = "<?php echo $jobtekerIP; ?>";
            var sentToExec = "<?php echo $sentToExececution;?>";
            var hasOutput = <?php echo json_encode($allOutputVarName);?>;

            $.getScript(scriptPath, function(data, textStatus, jqxhr) {

                var jobBatchID = "<?php echo $jobsArray[0];?>";
                var jobID = "<?php echo $jobsArray[1];?>";
                var jobName = "<?php echo $jobsArray[2];?>";

                // execute a function inside the script has no input parameter
                if (typeof hasInput !== 'undefined' && hasInput === 'no'){
                    // execute a function inside the script with no input parameter

                    var arrayFromPHP = <?php echo json_encode($newAllInputVarPath);?>;
                    for (var i = 0; i < <?php echo sizeof($newAllInputVarPath);?>; i++) {

                var jobID = "<?php echo $jobsArray[1];?>";
                var jobName = "<?php echo $jobsArray[2];?>";
                var sentToExec = "<?php echo $sentToExececution;?>";

                $.ajax({        
                        type: 'POST',
                        data: {results : result, job_batch_id : jobBatchID, job_id : jobID, job_name : jobName, sentToExec: sentToExec, jobExecIp : jobExecIp, execMessage : execMessage},
                        cache: false,
                        url: 'executedJobs.php'
                    });
            });
        }
    });
</script>

The problem is that my post under the comment “executes the POST if everything is ok” sends empty parameters if the function that I'm executing using var returnVar = <?php echo $newJobName; ?> var returnVar = <?php echo $newJobName; ?> or var returnVar = <?php echo $jobsArray[2]; ?>.apply(this, vars); returnVar = <?php echo $jobsArray[2]; ?>.apply(this, vars); has var maxNum = 500000; and var arrayMaxSize = 500000; . When I look in the console under the parameter window of the POST to executedJobs.php , I the right results there just not on the view window of the and of course not on the executedJobs.php page itself. And this is the function that is being called by the var returnVar

function job1() {
    var notSortNumArray = [];
    var notSorted1 = [];
    var notSorted2 = [];
    var maxNum = 500000;
    var arrayMaxSize = 500000;
    var minNum = 1;
    // create an array with arrayMaxSize random nmber between minNum and maxNum
    for (var x = 0; x < arrayMaxSize; x++) {
        notSortNumArray.push(Math.floor(Math.random() * (maxNum - minNum)) + minNum);
    }
    // The notSorted1 is from possition 0 untill random between 0 and arrayMaxSize
    notSorted1 = notSortNumArray.slice(0, Math.floor(Math.random() * notSortNumArray.length));
    // The notSorted2 is from where the notSorted1 ends untill the last number form the notSortNumArray
    notSorted2 = notSortNumArray.slice(notSorted1.length, notSortNumArray.length);
    // job dependencies
    var nextJob = "job2, job3";
    var prevJob = "null";
    // results
    return [ notSortNumArray, arrayMaxSize, notSorted1, notSorted2 ];
}

Funny thing is that for var maxNum = 250000; and var arrayMaxSize = 250000 everything works perfect and all the results are being sent to the executedJobs.php page for further.

Again I hope someone can help me solve this since I don't have a clue why it's not working for higher numbers of the var maxNum and the var arrayMaxSize parameters, the results are there they and something is being sent to the executedJobs.php page but nothing comes over.

I know this is a lot of code, but I hope someone can help me solve this since I don't have a clue why it's not working.

No semicolon at lines :

var scriptPath = "<?php echo $jobJSPath[0]; ?>" 
var execMessage = "An unknown falure has accourd while executing, will be executed once more"

in line :

var hasOutput = <?php echo json_encode($allOutputVarName);?>;

you should change it to :

var hasOutput = JSON.parse("<?php echo json_encode($allOutputVarName);?>");
