calling php function in jquery

Question

I have one file json.js and one php function in php file .in json.js i want to check value returned by php function if value returned by function is 0 jquery should perform :$(':input').prop('disabled', true); otherwise nothing –

function loadJson (table, id) {
 $.get("json-object.php", {'table': table, 'id':id}, function (data) {
 console.log(data);
 $.each(data, function (k, v) {
 if ($('input[name="'+k+'"]').is('input[type="text"]')) {
 $('input[name="'+k+'"]').val(v);
 } 
 if($('select[name="'+k+'"]').val(v)){
 get_input_value(k,v); 
 } 
 if ($('input[name="'+k+'"]').is('input[type="checkbox"]')) {
 get_input_value(k,v);
 } 
 console.log(k+' ==> '+v);
 // Here I want to check condition of php function if value returned by fucntion is 0 it should perform :$(':input').prop('disabled', true); otherwise nothing //
 });
 }, 'json');
}

My php function:

function ronly($id) {
 //$id=$_POST['noces'];
 $sql = "SELECT COUNT(noces) FROM alterdetail WHERE noces = '$id'";
 $sql.=';';
 //echo "QUERY <br/>";
 //echo $sql;
 $res = mysql_query($sql);
 $row = mysql_fetch_array($res);
 if($row['COUNT(noces)'] > 0)
 { echo "you can not alter data";
 return 0;
 }
 else
 {
 echo " data new ";
 return 1;
 }
 }

• Ja͢ck: Is the return value from PHP added in the AJAX response somehow?

Answer 1

You can't, as Javascript is client-side executed, and PHP is server-side executed ...

A "solution" would be to assign a Javascript variable into the PHP file that you'll read into the Javascript file, as variable are global.

Answer 2

Use jQuery if possible.

$('#result').load('ajax/test.php', function() {
 alert('Function called');
});

Or try JQuery forms. Use a form to submit any data, and it'll give you the response as a text or JSon object.

http://jquery.malsup.com/form/#ajaxSubmit

Here is an example for you:

$('#anyForm').ajaxForm({
 url: "process.php?proc=7",
 dataType: 'html', 
 success: function(responseText) {
 if(responseText == "0") { 
 $(':input').prop('disabled', true); 
 }
 } 
});

• user1464087: what is sellform here ? process.php is the file where i have my php function . data type should be html ok . in success can i use my condition in place of function ?
• Lakatos Gyula: #sellForm is a <form>. You can do: if(responseText === 0) { $(':input').prop('disabled', true); } instead the alert. If that's what you want.
