从wordpress中的ajax调用返回javascript

Question

I'm trying to return some javascript from an ajax response, Everything seems to be ok but still, I'm getting an error. Here's my code:

function class_fees_settings(){
    global $wpdb;
    $class_id = $_POST['value'];
    $fees_table = $wpdb->prefix."wpsp_fees_settings";
    $sql_res = $wpdb->get_results("SELECT * FROM $fees_table WHERE cid = '$class_id'");
    foreach ($sql_res as $fee) :  ?>
        <script type="text/javascript">
            $("#fs-adm").val("'<?php echo $fee->admission_fees; ?>'");
            $("#fs-tution").val("'<?php echo $fee->tution_fees; ?>'");
            $("#fs-trans").val("'<?php echo $fee->$transport_chg; ?>'");
            $("#fs-annual").val("'<?php echo $fee->annual_chg; ?>'");
            $("#fs-recreation").val("'<?php echo $fee->recreation_chg; ?>'");
        </script><?php 
    endforeach;
    wp_die();
}

I also tried to assign values to an variable inside loop like $adm = $fee->admission_fees and then echoed the $adm but this is giving me an error and then I directly echoed the $fee->admission_fees , it is working fine. Also I'm not getting any proper error message in console or page instead getting an error 500 Internal Server error in chrome Network tab Where all my XHR s are listed

Answer 1

There is an error in line no. 10 remove $ sign before transport_chg

$("#fs-trans").val("'<?php echo $fee->transport_chg; ?>'");
