javascript - How to get id and type in php foreach loop and send to server via ajax? -

so have 2 files index.php , changelikedislike.php. think issue javascript trying type , id not know how go that. javascript function being called in foreach->li->divs. working before this: data: datastring, added schoolid data of ajax it's data: {datastring:datastring, schoolid:schoolid},

index.php

<?php                 $last_id = 0;                 foreach ($list $rs) {                     $last_id = $rs['id']; // keep last id paging                     ?>                     <li>                         <div style="width:100%; color:#000;">                             <?php echo '<div class="product_like thumb-div"><img src="like.png" class="rating-image " onclick=changelikedislike("like","'.$rs['id'].'")> <br><span id="product_like_'.$rs['id'].'">'.$rs['plike'].'</span></div>';?>                             <?php echo '<div class="product_dislike"><img src="dislike.png" class="rating-image" onclick=changelikedislike("dislike","'.$rs['id'].'")><br> <span id="product_dislike_'.$rs['id'].'">'.$rs['pdislike'].'</span></div>';?>                         </div>                     </li>                     <?php                 }                 ?>  <script type="text/javascript"> //begin , dislike function changelikedislike(type,id){   var datastring = 'id='+ id + '&type=' + type;   $.ajax({   type: "post",   url: "changelikedislike.php",   data: {datastring:datastring, schoolid:schoolid},   cache: false,   success: function(result){            if(result){                 console.log('working');           }     }   });//end ajax } 

schoolid works in data not datastring in ajax how go grabbing those. php file reference:

//checks if school page id brought , stores variable if (isset($_post['schoolid'])) {     $schoolidfinal =  $_post['schoolid']; }else {     echo "nope"; } if (isset($_post['type'])) {     $type =  $_post['type']; }else {     echo "nope type"; } if (isset($_post['id'])) {     $id =  $_post['id']; }else {     echo "nope id"; } 

my page echoing out "nope type nope id"

please change

data: {datastring:datastring, schoolid:schoolid}, 

to

data: {type:type, id:id, schoolid:schoolid}, 

to match params php script.

data can either query string (like datastring) or json struct (like {type:type, id:id, schoolid:schoolid}).

see documentation of jquery.ajax(): "the data option can contain either query string of form key1=value1&key2=value2, or object of form {key1: 'value1', key2: 'value2'}."
