ajax返回成功但mysql db没有更新

Question

I have a javascript for loop that sends an array to an ajax page to update the mysql database.

I echo the result back to the original page and it echos as a success but when I check the db nothing has changed

my javascript for loop that sends the array

for(var m=0; m<array.length; m++){
    $.post("update_page_positions.php",{page_ref:array[m][0], ref:array[m][12], menu_pos:array[m][1], sub_menu_pos:array[m][2], top_menu:array[m][3], pagelink:array[m][4], indexpage:array[m][5], hidden:array[m][6], page_title:array[m][7], page_desc:array[m][8], page_keywords:array[m][9], page_name:array[m][10], deletedpage:array[m][11]},         
        function(data,status){  
            alert("data="+data+" status="+status);   
});                 

here is the php ajax page the updates the db

<?
    include("connect.php");     
    $ref = $_POST['ref'];
    $page_ref = $_POST['page_ref'];
    $menu_pos = $_POST['menu_pos'];
    $sub_menu_pos = $_POST['sub_menu_pos'];  
    $top_menu = $_POST['top_menu'];
    $indexpage = $_POST['indexpage'];       
    $page_name = $_POST['page_name'];    
    $page_title = $_POST['page_title'];
    $page_desc = $_POST['page_desc'];   
    $page_keywords = $_POST['page_keywords'];   
    $hidden = $_POST['hidden']; 
    $pagelink = $_POST['pagelink']; 
    $deletedpage = $_POST['deletedpage'];   

    $query = mysql_query("SELECT * FROM pages WHERE ref='$ref' AND page_ref='$page_ref'");

 if(mysql_num_rows($query)==0){
    mysql_query("INSERT INTO pages(page_ref, ref, page_name, menu_pos, sub_menu_pos, top_menu, link, indexpage) VALUES('$page_ref','$ref','$page_name','$menu_pos','$sub_menu_pos','$top_menu','$pagelink','$indexpage')");
}

 if($deletedpage=="1"){
        mysql_query("DELETE FROM pages WHERE ref='$ref' AND page_ref='$page_ref'");         
        mysql_query("DELETE FROM site_content WHERE ref='$ref' AND page_ref='$page_ref'");
 } 
 else{       
       if(mysql_query("UPDATE pages SET menu_pos='$menu_pos', sub_menu_pos='$sub_menu_pos', top_menu='$top_menu', indexpage='$indexpage', page_name='$page_name', page_title='$page_title', desc1='$page_desc', keywords_list='$page_keywords', hidden='$hidden', link='$pagelink' WHERE ref='$ref' AND page_ref='$page_ref'")){

        echo "updated!";
     } else{
        echo "error";           
      }

 }   
?>

the INSERT and DELETE functions are fine but the UPDATE returns a success statement but does not update the db.

Can anyone see what the problem is?

Answer 1

Posted as an answer because the comment was too hard to read:

Rather than echoing "updated", try echoing

"UPDATE pages SET menu_pos='$menu_pos', sub_menu_pos='$sub_menu_pos', top_menu='$top_menu', indexpage='$indexpage', page_name='$page_name', page_title='$page_title', desc1='$page_desc', keywords_list='$page_keywords', hidden='$hidden', link='$pagelink' WHERE ref='$ref' AND page_ref='$page_ref'"

(ie. the query you're trying to run).

See if that gives you some clues.
