setting global variables

svihas

Hi,

I want to have some form variables as array and available to 4 follwing pages.
First I tried with one variable, but I failed in the start itself.

ex:
page1.php
<?
session_start();
session_register("category");
$category = "testvalue";
....
?>

page2.php
<?
session_start();
echo $category;
....
?>

page3.php
<?
session_start();
echo $category;
....
?>

When I open page1.php from page0.html this error message I get,
Warning: open(/tmp\sess_e059802b8922f1390d65222a63c37781, O_RDWR) failed: m (2) in c:\ora817\apache\apache\htdocs\mhptest\page1.php on line 4

then, displays all html page

then another error message,
Warning:
open(/tmp\sess_e059802b8922f1390d65222a63c37781, O_RDWR) failed: m (2) in Unknown on line 0

Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

Do I need to set any thing in PHP.ini file?

In Php.ini, the session.savePath is /tmp.

Could someone help?

Thanks

You might want to change the session.savePath to C:\TEMP or something similar since it appears you are running on Windows and not Unix.

Thank you
I changed ini file and created temp directory, it worked fine.

I could catch the value that is assigned directly in following 3 pages. Now I tried with form elements. ?But I failed.

ex:
page1.php
<?
session_start();
session_register("form1_val");
$form1_val= array($id_1,$id_2,$id_3);
....
?>

...<FORM METHOD="post" name="entry1" ACTION="page2.php"
onsubmit="return chkfield(this);">
value1:<INPUT TYPE="text" NAME="id_1"><br>
value2:<INPUT TYPE="text"NAME="id_2"><br>
value3:<INPUT TYPE="text"NAME="id_3"><br>
...

page2.php
<?
session_start();
echo $form1_val['id_1'];
echo $form1_val['id_2'];
echo $form1_val['id_3'];
session_register("form2_val");
$form2_val= array($id_1,$id_2);
....
?>

...<FORM METHOD="post" name="entry2" ACTION="page3.php" >
value1:<INPUT TYPE="text" NAME="id_1"><br>
value2:<INPUT TYPE="text"NAME="id_2"><br>
...

page3.php
<?
session_start();
echo $form1_val['id_1'];
echo $form1_val['id_2'];
echo $form1_val['id_3'];
echo $form2_val['id_1'];
echo $form2_val['id_2'];
....
?>
........

If you get the picture, nowhere I could catch or display the values. I am able to catch them directly as $id_1 in next page as I am posting them, but not thru' the session variable. I could use hidden type and catch them in following page, but I want to have them in array as they are in variable number of form element values, I couldn't know howmany in the beginning except the maximum
number of input fields.

I tried initializing session in page2 also as some of the variables already available. but no use.

Any help is appreciated.
Thanks

If I'm looking at it right, you never really set the values.

When you are initializing the array $form_val1 on page 1, there are no values to $id_1 and such. I think you need to place that code on the beginning of page 2 after the session start, but before the echos.

Try this...

page1.php
<?
session_start();
?>

...<FORM METHOD="post" name="entry1" ACTION="page2.php"
onsubmit="return chkfield(this);">
value1:<INPUT TYPE="text" NAME="id_1">
value2:<INPUT TYPE="text"NAME="id_2">
value3:<INPUT TYPE="text"NAME="id_3">
...

page2.php
<?
session_start();
session_register("form1_val");
$form1_val= array($id_1,$id_2,$id_3);
?>

any_other_page.php
<?
session_start();
echo $form1_val['id_1'];
echo $form1_val['id_2'];
echo $form1_val['id_3'];
?>

Hi,
I made mistake in assigning form values to an array. I modified the code and I could catch all variables from following pages. The changes I have given below:
ex:
page1.php
<?
session_start();
session_register("form1_val");
$form1_val= array(1=>$id_1,2=>$id_2,3=>$id_3);
....
?>

page2.php
<?
session_start();
echo $form1_val[1];
echo $form1_val[2];
echo $form1_val[3];
session_register("form2_val");
$form2_val= array(1=>$id_1,2=>$id_2);
....
?>

...<FORM METHOD="post" name="entry2" ACTION="page3.php" >
value1:<INPUT TYPE="text" NAME="id_1"><br>
value2:<INPUT TYPE="text"NAME="id_2"><br>
...

page3.php
<?
session_start();
echo $form1_val[1];
echo $form1_val[2];
echo $form1_val[3];
echo $form2_val[1];
echo $form2_val[2];
....
?>
........

It's working fine.

Hi,
Sorry, session has to start in page2 only, not in page1.

I am working on an assignment that uses php. I have written two pages. One is php that prints out html. This pages accepts input from a form. The second page is like the action page that gets information from the previous pages. My problem is when the submit button is pressed on the first page, and then it goes the second pages. The second page will output nothing. What do I need to change, or what am I doing wrong?

Thanks
