Question

id doesn’t want to put the value in to the document.getElementById("UniLoc").value = val; and it doesn’t want to submit the form how to fix this ?

This is how I call the function JS nas some value “asd56”

 echo "
 <script type="text/javascript">
    repostD("'.$JS.'");
 </script>";

here is my function inside

<script>
function repostD(val)
{   
   //document.getElementById("UniLoc").value = val;
   document.getElementById('UniLoc').innerHTML = val;
   //document.UlRL.UniLoc.value = val;
   document.forms["UlRL"].submit();
}
</script>

and here is my form in html

<form name="UlRL" id="UlRL" action="in.php" method="post">
<input type="text" id="UniLoc" name="UniLoc" value="<?php echo $UniLoc;?>" />

Answer 1

try doint that in php all instead of in function make an if clause down the code that will execute the action of the posting of the form and at the beggining of the php try this

 if($JS!="" )
 {

 $UniLoc=$JS;
 $JS="something that will go throught the other if down at the code";

  }
 else {

  $UniLoc=$_POST["UniLoc"];
 }
