check value of 1 or 0 in db and redirect

[ianhaney]

Hi

 

Sorry

 

I have been trying to work this one out for a while, in a php page, I want to be able to have the php page check if a db table column has a value of 1 in the paid column and if it has to stay on the same php page and if it has a 0 to redirect to another php page

 

Is that possible?

 

Thank you in advance

This may be semantics but what you are saying is you want a script to check a db table and depending upon what it is, go to a specific page. As you wrote it you make it sound like you are doing this while looking at the page which you can't do since php is running server-side. Of course the whole idea is elementary. Do your query. Write an if statement. Make a header() call to the appropriate script/page.

Thank you for the reply, appreciate it

 

I was thinking if it would be something like the following

<?php if($paid == 1) {
header:  (stay on page);
} else {
header: (redirect to another page);
?>

Knowing me I am prob way off

You don't need a header to stay on the same page. Check if $paid == 0; if it does, redirect the user. If not, just continue the script execution on that page.

[ginerjm]

You need to be careful how you use the words page and script. The script is where your code resides. IMHO, the 'page' is what you see on the client screen.

 

When your code above executes you make a choice between showing page 1 or page 2. Now if the script is triggered from a URL then the two headers that you propose are correct. If you are in the running script with the above code because say, page 1, triggered it, and your script decides that page 1 needs to be displayed again, then let your script do that like it already did perhaps. If the other page is desired, then the header call will do it for you.

 

This question makes me wonder what you are thinking about since it is a pretty elementary concept.

Hmm think I have got it wrong somehow

 

it don't seem to go to the job advert page, it redirects to the profile page instead, it don't seem to be checking the script, below is what I have at the top of my php job advert page

<?php
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);

// connect to the database
include("connect-db.php");

if($paid == 0) {
header("Location: employer-profile.php");
}
?>

Sorry will remember to say either page or script

 

It does seem simple but I can't work it out

I am guessing it is to do with another post of yours (http://forums.phpfreaks.com/topic/300074-paypal-payment-access-page-issue/?do=findComment&comment=1528883). If so it is not helpful for others if you keep spreading the problem over separate posts so that we have to search the forum for relevant information

[ianhaney]

Sorry yeah is related to that one but think I sussed that issue on the forum post below as it is updating in the db table

Where is $paid given a value? Your posted code doesn't set it here. And if as Barand says you have code elsewhere, I will step away since I don't like to waste my time.

I now have the following script in the job advert php page and payment has been completed as has a 1 in the paid column in the db table but it still redirects to the profile page instead of staying on the job advert page

 

below is the whole script from the job advert php page

<?php
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);

// connect to the database
include("connect-db.php");

$paid = '';

if($paid == 0) {
header("Location: employer-profile.php");
}

?>

<?php require('config-db-employers.php'); 

//if not logged in redirect to login page
if(!$user->is_logged_in()){ header('Location: employer-login.php'); } 

?>

<?php
/*
Allows the user to both create new records and edit existing records
*/

// connect to the database
include("connect-db.php");

// creates the new/edit record form
// since this form is used multiple times in this file, I have made it a function that is easily reusable
function renderForm($memberid = '', $ref = '', $role ='', $division ='', $location ='', $salary ='', $description ='', $datecreated ='', $dateupdated ='', $error = '', $id = '')
{ ?>

<?php

$title = "Add/Edit Job Advert - Security Site";

$paid = '';

if($paid == 0) {
header("Location: employer-profile.php");
}

$paid will never equal 0 if you just set it to an empty string the line above the if() statement...

Actually, doing that means $paid is always == 0 (but not === 0)

$paid = '';
if ($paid == 0) {
    echo "Not paid";  // always echoes
}

That's what I get for posting early in the morning. Good point.
