mysql查询无法通过php工作 由phpmyadmin工作

Question

One of my PHP functions just not work. Mysql returns success but it doesnt UPDATE column that i want. I really no have idea why that problem exist.

So here is the function that UPDATING it:

function savePhone($phone) {

 dbConnect(); $q = "UPDATE site SET phone = '$phone' WHERE id = 0"; $r = mysql_query($q) or die (mysql_error()); if ($r) return $q; else return "error"; 

}

Here is var_dump-ed example query that works fine when using phpMyAdmin.

'UPDATE site SET phone = '111111' WHERE id = 0'

Im using Apache

Answer 1

This is wrong actually die() stops the script from executing

$r = mysql_query($q) or die (mysql_error());

if die() is called this part is never gonna be executed and no value is returned to $q

if ($r) return $q; 
  else return "error"; 
}

use instead

$r = mysql_query($q);

if(empty(mysql_error())) return $q;
   else return "error";
