Foreach help

[crazyfrog]

Hi,

 

Can anyone see a problem with this bit of code?

    <?php
session_start();
foreach ($_SESSION['_amember_subscriptions'] as $sub);   //This is line 53
if ($sub['payment_id']){
  $diff = (strtotime($s['expire_date']) - time()) / (3600*24);
  if ($diff > 0){
     print "Your subscription expires in $diff days";
 print ("$sub");
  }
}
?>

 

I am getting the following error and cant understand why. reading through other topics, i seem to think it is something to do with arrays?

Warning: Invalid argument supplied for foreach() in /home/*****/public_html/tester.php on line 53

 

Thanks

<?php session_start();

$x=$_SESSION['_amember_subscriptions'];

foreach($x as $sub){

if ($sub['payment_id']){

$diff = (strtotime($s['expire_date']) - time()) / (3600*24);

if ($diff > 0){

print "Your subscription expires in $diff days";

 print ("$sub");
  }
   }
     }
?>

Still getting the same error 

 

That was a damn fast reply though!

foreach ($_SESSION['_amember_subscriptions'] as $sub);  //This is line 53

 

 

Warning: Invalid argument supplied for foreach() in /home/*****/public_html/tester.php on line 53

 

this is caused when $_SESSION['_amember_subscriptions'] is not an array.  You may want to double check this.

 

Also, giving a line like

foreach ($_SESSION['_amember_subscriptions'] as $sub);  // this is meaningless

because you terminated the foreach loop with the semicolon ';' before it can actually do anything:

 

foreach ($_SESSION['_amember_subscriptions'] as $sub)

{

  // your code here

 

}

this is caused when $_SESSION['_amember_subscriptions'] is not an array.  You may want to double check this.

 

 

How would i find out?

[hvle]

var_dump(is_array($_SESSION['_amember_subscriptions']));

if you have bool (true), it is an array, false mean it is not.

[crazyfrog]

Damn, its not!

 

Any remedies?

[hvle]

if it is not an array, there is no point to use foreach loop isn't it?

[crazyfrog]

Thanks for all your help, but i am new to php and am finding it quite interesting.

 

would i just remove foreach from the code then?

[hvle]

Your code expect $sub to be an array as well.  So, I am sure if you remove the foreach, it still won't work.

[crazyfrog]

Ah well.

Really needed this to work.

Thankyou very much for all your help.

How are you setting the session value?

How are you setting the session value?

I dont quite understand?

I am trying to add a line of text to my site something like "Your subscription will end in ** days"

[kenrbnsn]

You want to use "$_SESSION['_amember_subscriptions']". How/where are you putting something into this session variable?

 

Ken

[crazyfrog]

It is created in mysql when the user subscribes for a selected period.

Hope this is what you mean

[kenrbnsn]

Please post the code that sets the value.

I think i will leave it, i can see this getting too technical for a N0ob. :'(

I wouldnt know where to look.

Thankyou

Please post the code that sets the value.

Would this be something like the signup.php page source?
