[SOLVED] Passing variables

[Suchy]

How can I pass a variable ( event id) to a different page when a button is pressed?

The problem is that the events are listed via a loop, and when I use sessions the event session always contains the id of the last event on the list.

 

The only other way I can think of is adding

onclick="window.location.href='login.php?event=<?php echo $id;?> ' 

and then just pulling the id from the url

 

 

 

Is there a different way ??

What's wrong with that?

It's the best way of doing it. See that big url up there? Even this forum does it.

If it's a button you can use a form with a hidden field for this value.

Wouldn't it be the same as with Sessions, if by each button I had a hidden filed, ex:

<input name="event_id" type="hidden" value="<?php echo $id; ?>" />

and if I pressed on a button for example in the middle of the list, the event_id would always be that one of the last element.

What?

If it's in a loop, just assign each input the id relative to the current record/whatever you're looping.

But on the login.php how would I know what to use if the hidden fields are like:

 

<input name="1" type="hidden" value="<?php echo $id; ?>" />

<input name="2" type="hidden" value="<?php echo $id; ?>" />

<input name="3" type="hidden" value="<?php echo $id; ?>" />

<input name="4" type="hidden" value="<?php echo $id; ?>" />

What exactly are you trying to achieve?

[Suchy]

I have a events.php page with a list of events (ex. Word class, Powerpoint class ... ), by each I have a register button. What I want is that when someone hits the register button he will be taken to the login.php page, where it will say something like "To register for event $$$$$ please fill out the form".

 

$$$$$ would be the value of the variable that I want to pass from the previous page.

 

[Mchl]

And how do you create this list of events?

[Suchy]

I used Ajax to call a function to save the sellected event id in a session, that works for me.

 

Dzięki za pomoc Mchl.
