Problem with script structure ???

DavidinLondon · #1 (**permalink**) Jun 9th, 2006, 06:23

I am having a problem getting my script to continue processing after calling (request_once) another script.

There are three scripts involved.
Main one (Homes_add.php) calls the second (a_picts.php) which is a form validating script - which ofcourse calls its form (a_picts_fm.php)

Again - it is clear that the problem is not in returning from a_picts_fm back to a_picts - BUT the problem is returning from a_picts back to the main script ( homes_add script.)

I wonder if there is a fundamental structural problem ?

The main script (homes_add)
calls ( require_once ) the a_picts which processes the form.
The form itself on submisson re-runs the a_picts which when finshed should return to the main script (homes_add) and continue from where it left the off.

To summarise the problem is that the a_pict.php stops at the last line afer executing this :

echo " *** and got here";

IT DOESN'T RETURN TO HOMES_ADD.PRG

- dont know why ???

I have stripped a lot of the code to try and make it clearer.

If anyone can help - I'd much appreciate it as I am a bit stuck !

HERE IS THE MAIN - HOMES_ADD.PHP SCRIPT
IT CALLS THE PICTURE HANDLING SCRIPT

PHP: Select all


  <?php 
/*  
*  homes_add.php 
* 
* Called by :  homes_ad_btn.php 
* 
* Call  a_picts.php to get the pictures 
* 
*  processes the  homes_add_fm.php  which is the 
*   FORM for adding a home. 
*/ 
           
if (!isset($_POST['run_mn'])){     

PREPARES DATA AND CALLS THE MAIN FORM ( NOT PICTURE FORM) 

else  {   // BIG else    -  SO MAIN FORM HAS RUN  

   VALIDATES FORM DATA 

/* 
*  Now we get the pictures. 
*/ 
    if( $pict ==  "y"){       
       require_once("a_picts.php");   //  < --   HERE IS THE CALLING  
       exit();                              //   < -- I TRIES TAKING THIS OUT           
         }  // endif  
    else{ 
       $N_pix1=$N_pix2=$N_pix3=$N_pix4=$N_pix5="none"; 
         } // end else 

    //  I WANT TO RETURN BACK HERE  
          
$sql =  "UPDATE homes SET 
         pix1 = '$N_pix1',  
         pix2 = '$N_pix2', 
         pix3 = '$N_pix3', 
         pix4  = '$N_pix4', 
         pix5 = '$N_pix5'  
                                              
     WHERE ad_ref =  '$A_ref' "; 
      
     mysql_query($sql) 
    or die("could not execute HOMES UPDATE PICTURES query"); 
          
/* 
*  Update  the client table 
*/ 
        ETC ETC 
       
} // end BIG else  
?>
</div>

THIS IS THE SECOND SCRIPT THAT CALLS AND THEN PROCESSES
THE FORM

PHP: Select all


  if(isset($_POST['run'])){  // BIG IF  

     PROCESSES THE PICT_FM.PHP   FORM 

   echo "got here"; 
}  // end BIG IF  

else    { 
    $message1 = "none"; 
    $message2 = "none"; 
     require_once  ("a_picts_fm.php");    //  CALLS THE FORM  
     exit(); 
    } // end else 

echo " *** and got here";      //  THIS WHERE IT STOPS 

?>

</div>

AND THIS IS THE FORM THAT THE ABOVE REQUIRES

PHP: Select all


<?php 
/*  
* picts_fm.php 
* 
* Called by : picts.php 
* IT THEN GOES BACK TO  PICTS.PHP 
* 
* FORM for adding images. 
* 
*/

Are the files definately being included and do you definately have display_errors turned on in your php.ini file? If the screen is just white it could be that they are not being included and you have display_errors turned off.
