[PHP] Question

Hi guys,

I need to integrate some PHP code into my templates. I need to define some variables in the beginning of the template and then apply these variables throughout the template. The problem is that when you close the [PHP] or open new one, I'm not sure - the value of the variable is lost.

Does anyone have any tips on how to avoid this?

Thanks in advance!

can you use:

[PHP]include ();[/PHP] ?

and then place the code in a new php file...?

Hi Frold, thanks for your quick reply.

Unfortunately this won't work. Here is what I have.
In the beginning of the template I generate a random number from 1 to 3

Code: Select all

$option = rand(1,3)

Then in 2 different places I have to use the generated random number to display an image from 1.gif to 3.gif and in the second place include an HTML file from 1.html to 3.html

Thank you!

Hi,

perhaps try this:

first make your random number global

[PHP]
$_SESSION['MyRandom'] = rand(1,3);
[/PHP]

And than you can call it everywhere and everytime:

[PHP]
echo "<img src='".$_SESSION['MyRandom'].".jpg'>";
[/PHP]

Random + Image = ...

Whats with RT {RANDOM:picture/1to3} using in your templates?
Save your 1..3.gif in an folder "1to3" and ready... (I hope)

This won't work unfortunatelly, because I also have to include a random HTML file that corresponds to the random loaded image. So lets say random image is 2.gif then the include file has to be 2.html

Using sessions like cwenet recommended seems to make the most sence.
Thank you all for your input!
