carrying variables over to other files

levans

Hey, nice site..

if i have 2 files (a.php and b.php)

---a.php----

<? $user = "me"; ?>

----b.php---

<? echo($user); ?>

how do i do this, i tried using include(a.php) but that includes the whole script, i just want to use the value of $user in b.php.

Thanks

Well, you'll have to pass it somehow. Post, Get, Sessions, Cookies, Database, Flat File, something.

thanks for the quick reply! ..but..

I have passed it using forms before, using :
$user = $_POST['uname'];

but this when i have submitted a form so the variables from the form are available. I am trying to get the variables from one file that has no form...

could somone show me a quick example if they have time..

thanks

I'd do that like this:
- if the variable is not simple (I mean a string or an integer) but an array for example, use serialize() to make it "store-able"
- save it in a file (fopen(), fwrite(), fclose())
- when you want to read it, read it from file (fopen(), fread(), fclose()) and unserialize() it.
If you want to store a user id data, a better idea would be to use cookies (or sessions).

As long as it's not sensitive, use get. You have to somehow get from a.php to b.php, just tack it on to the url.

ok thanks for the help ppl!

next question is can i put the following HTML inside the php script?

<a href="edit.php?name=<?=$user?>">Modify one of my contacts</a>

if so how can i do this without the '?' characters messig everything up..

thanks

If I understand you correctly, it should be...

?> <a href = edit.php?name=<?php echo $user ?>>Modify one of my contacts</a>

If you'll notice the majority of it is written in html rather than php... you close the php script at the beginning, begin the html hyperlink, then when you need to input the variable you begin a new php script have it return the variable $user, Close that php script, close the A tag, type in the text to be displayed as the hyperlink and end the hyperlink.

i just woke up, so I hope i'm right

my fault, poor explanation....

here is what i meant...

<?php

blah blah blah ...

if(this this condition)
{

//i only want to display this link here if the condition ablove is met.

<a href="edit.php?name=<?=$user?>">Modify one of my contacts</a>

}

hopefully this is a better exaplanation, i only want to display the link if a condition is met in php.

thanks,

😃

<a href="edit.php?name=<?=$user?>">Modify one of my contacts</a>

should read

<a href="edit.php?name=<?$user;?>">Modify one of my contacts</a>

Drop the equals and include a semicolon and it should work.

levans

sorry again, it didnt work..

i also meant to tell you that i want to print it or echo it...

such as..

echo("<a href="edit.php?name=<?=$user?>">Modify one of my contacts</a> ");

or...

print("<a href="edit.php?name=<?=$user?>">Modify one of my contacts</a> ");

any suggestions?

Actually, cjhowe, <?=$user?> is correct, though should be avoided, in my opinion.

The problem is that the string is being placed wrongly.
It should be:

echo "<a href=\"edit.php?name={$user}\">Modify one of my contacts</a> ";

Notice that the double quotes within the double quote delimited string have been escaped.
