[Resolved] $_session

rathersurf

how would i put the 'NAME' below into a $_SESSION array???

printf("<option value='%s'>%s</option>\n", htmlentities($row['SCHOOL']), htmlentities($row['NAME']));

and then print the result later on???

Thanks in advance..

Rathersurf,

Well first you have to have your pages start the session. I will demonstrate:

<?php
session_start();

$_SESSION['GLOBAL_NAME'] = "PHP Rulz";
?>

Then whenever you need GLOBAL_NAME just use it:

<?php
session_start();

echo "$GLOBAL_NAME";
echo "-OR-";
echo "$_SESSION['GLOBAL_NAME']";
?>

That should take care of things. I don't know if register_globals needs to be on to use $GLOBAL_NAME without the identifier but it might be. See all the documentation on sessions at: http://us3.php.net/manual/en/ref.session.php

Thanks so much and keep coding!

I have session_start(); at the beginning of my pages..... and i know that i need to set a variable using $_SESSION just like you displayed

$_SESSION['GLOBAL_NAME'] = "PHP Rulz";

i just dont get how do i set this line.....

printf("<option value='%s'>%s</option>\n", htmlentities($row['SCHOOL']), htmlentities($row['NAME']));

which prints a drop down pulled from a db query.... i want NAME to be that variable so i can call the selected name anywhere i want...

Thanks Again

you need to [man]sprintf[/man] instead of [man]printf[/man].

session_start();

$_SESSION['var'] = sprintf("<option value='%s'>%s</option>\n", htmlentities($row['SCHOOL']), htmlentities($row['NAME']));

Is this what you're after?

$_SESSION['GLOBAL_NAME']="PHP Rulz";

printf("<option value='%s'>%s</option>\n", htmlentities($row['SCHOOL']), htmlentities($row[$_SESSION['GLOBAL_NAME']]));

rathersurf

I believe that is what i was looking for.....thanks again for all of your help...i dont have the app i was working on with me right now, i will check it later...

there is

rathersurf

i just tried both ways and neither one worked....devinemke your way made the drop down disappear completely....it wouldtn give me any options in my drop down menu....Cailean your way showed the drop down, with no values displayed but i could scroll through what appeared to be empty values, i could select an empty space where a school once was and i could pass the school that was selected, but no text was displayed so i couldnt tell what i was selecting...

Any suggestions on whats going on....

Thanks Again..

rathersurf

chads2k2 your way give me this error message.....

Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /srv/www/htdocs/test2.php on line 85

my way doesn't output anything, thus your drop down would disappear. my way simply captures the formatted string into a session variable, which is what i thought you wanted to do all along. can you explain in greater detail what you ultimately want to do.

rathersurf

ok....I have this line of code that displays a drop down ......

printf("<option value='%s'>%s</option>\n", htmlentities($row['SCHOOL']), htmlentities($row['NAME']));

it is assigning the value school and displaying the value name in the drop down ... which i pulled in a query from an oracle db....

this is on my functions page... in my test2.php page i simply have this piece of code which prints the function off of the functions page...where that line of code above is located... I want the displayed >> htmlentities($row['NAME']) << to be in the $_SESSION array so after the schoolchoice() drop down finishes executing and refreshes with the teacher drop down.... i want to be able to print that above the next drop down static without having to run another query ..... and the same thing on the third drop down just printing the NAME above the student drop down...

<?
schoolchoice();
?>

All the drop downs work fine....I just dont understand how to assign the $_SESSION array to >> htmlentities($row['NAME']) <<
so i can print that wherever i want...

if i confused you im sorry i can try to explain differently.....

thanks again for all of your help...

devinemke

why don't you simply stick the entire row into the session?

$_SESSION['row'] = $row;

then you can use that for whatever output purposes you want elsewhere on the current or subsequent pages.

rathersurf

Is this what your talking about....

printf("<option value='%s'>%s</option>\n", htmlentities($row['SCHOOL']), htmlentities($_SESSION['row'] = $row['NAME']));

then later i would

print $_SESSION['row'];

???

no. my point is this: you are building HTML output based on data stored in an array called $row. you want to re-use that same array later on on other pages. so put $row in a session and use the $_SESSION var to build all of you HTML output.

rathersurf

Sorry for being so dumb..... i am very new to all of this..... I am working on getting some php training..... until then i am trying to figure out alot of this on my own.... Is there any way you can show me an example.... Im not trying to get you to do this for me, i am just trying to get an understanding of how it is done ....

Thanks

devinemke

$_SESSION['row'] = $row;

printf("<option value='%s'>%s</option>\n", htmlentities($_SESSION['row']['SCHOOL']), htmlentities($_SESSION['row']['NAME']));

this same printf line can now be used on later pages by virture of the fact that it is stored in a session.

rathersurf

ok..im assuming that will still print my drop down list box for me.....if i wanted to display what was selected from that drop down at a later time "static text" not in a drop down I would just print

print $_SESSION['row']['NAME']);

sorry for any more confusion

no. what ever was returned from the form will be in the $POST or $_GET arrays (depending on which form method you are using)

rathersurf

ok this is what i have as an attempt to assign the variable

{

$_SESSION['schoolcode'] = $row['NAME'];
printf("<option value='%s'>%s</option>\n", htmlentities($row  ['SCHOOL']), htmlentities($_SESSION['schoolcode'] = $row['NAME']));

}

here is what i have to print it out

$GET['schoolcode'];
print $SESSION['schoolcode'];

all i get is the very last value in the drop down no matter what i select... Any suggestions ?
