Sessions in popup windows

bjblackmore

Hi,
I have a form, that checks a date, with day,mpnth,year i.e. 11/12/2001. When you press 'Check Date' day,month and year are registered as sessions. I want a popup window to popup, check the dates in a database and either say 'Yes We are Available' or 'Sorry We are not Available'. So I used javascript to get the popup, and i can get the popup to check the database, but how do I parse the sessions registered on page1 when you press 'Check Date', to the popup, so it can use those dates?
Regards
Ben

I beleve the session is automatically recognized in popup windows.
If not you can attach the session id as variabele to the filename you are calling in the javascript window opener and than in the openend file you use the session id in the session_start function to open the existing session.

If you need to know how, let us know.

(did u already try to do your session stuff in the same window, not in popup, to test if it works?)

Hi,
Thanks for replying. I have tried to use the session stuff in the popup window but didn't seem to work. I have a form, with javascript & php which looks like
<form action="javascript://" onsubmit="window.open(\'check.php?checkday='.$checkday.'&checkmonth='.$checkmonth.'&checkyear='.$checkyear.'\', \'winname\', \'width=300,height=100,menubar=no,resizable=no,toolbars=no\');">';
I was hoping this would open a page like check.php?checkday=12&checkmonth=12&checkyear=2001
This way I wouldn't have to worry about using sessions. Bit it doesn't work. So i tried
if ($submit){
session_register('checkday','checkmonth','checkyear');
}
Which didn't work either. So I tried just putting session_register at the bottom of the form, after </form> and this just registers the default in the 1st value in the drop menus, there are 3, checkday,checkmonth & checkyear, which people select the date they want to check from. But 01,01,2001 is always registered as its the 1st value.
Could you tell me how I'd use the session id please? I'd be very greatful.
Cheers

Can you give me the source code of both files than i can try some things?

bjblackmore

Yeah sure
This is the 1st file, where you select the dates.
session_start();

echo '<form action="javascript://" onsubmit="window.open(\'check.php?checkday='.$checkday.'&checkmonth='.$checkmonth.'&checkyear='.$checkyear.'\', \'winname\', \'width=300,height=100,scrollbars=no,menubar=no,location=no,status=no,resizable=no,toolbars=no\');" method="POST">';
echo '<div align="center">
<select name="checkday" value="'. $checkday .'">
<option value="01">01</option>
<option value="02">02</option>
<option value="03">03</option>
<option value="04">04</option>
<option value="05">05</option>
<option value="06">06</option>
<option value="07">07</option>
<option value="08">08</option>
<option value="09">09</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
<option value="13">13</option>
<option value="14">14</option>
<option value="15">15</option>
<option value="16">16</option>
<option value="17">17</option>
<option value="18">18</option>
<option value="19">19</option>
<option value="20">20</option>
<option value="21">21</option>
<option value="22">22</option>
<option value="23">23</option>
<option value="24">24</option>
<option value="25">25</option>
<option value="26">26</option>
<option value="27">27</option>
<option value="28">28</option>
<option value="29">29</option>
<option value="30">30</option>
<option value="31">31</option>
</select>
<select name="checkmonth" value="'. $checkmonth .'">
<option value="01">January</option>
<option value="02">February</option>
<option value="03">March</option>
<option value="04">April</option>
<option value="05">May</option>
<option value="06">June</option>
<option value="07">July</option>
<option value="08">August</option>
<option value="09">September</option>
<option value="10">October</option>
<option value="11">November</option>
<option value="12">December</option>
</select>
<select name="checkyear" value="'. $checkyear .'">
<option value="2001">2001</option>
<option value="2002">2002</option>
<option value="2003">2003</option>
<option value="2004">2004</option>
</select>
<br>
<input type="submit" name="check" value="Check Availability">
</div>
</form>';

And this is the 2nd file (the popup) that runs the query on the database.

session_start();

$sql="SELECT * from restaurant_availability WHERE date='$checkdate' && month='$checkmonth' && year='$checkyear'";
global $feedback;
$result=mysql_query($sql);
if(db_numrows($result) > 0){
$feedback .= ' We\'re sorry, The restuarant is fully booked on that date, You should have booked sooner! ';
} else {
$feedback .= ' Congratulations, we are availability on that date ';
}

if ($feedback) {
echo '<div align="center"><font face="Verdana, Arial, Helvetica, sans-serif" FONT COLOR="RED"><H5>'.$feedback.'</H5></FONT></div>';
}

If i enter the url of this file in manually, with the varialble, like..
check.php?checkday=12&checkmonth=12&checkyear=2001
It works fine, its just trying to parse the variables to this file!
Many Thanks for your help

I think as you said before the session is not needed.

see how i do it.

file 1:

<?php
if($check){
echo"<script>window.open('check.php?checkday=$checkday&checkmonth=$checkmonth&checkyear=$checkyear.', 'winname', 'width=300,height=100,scrollbars=no,menubar=no,location=no,status=no,resizable=no,toolbars=no');</script>";
}

echo "<form action=\"$PHP_SELF\" method=\"POST\">";
echo '<div align="center">
<select name="checkday" value="'. $checkday .'">
<option value="01">01</option>
<option value="02">02</option>
<option value="03">03</option>
<option value="04">04</option>
<option value="05">05</option>
<option value="06">06</option>
<option value="07">07</option>
<option value="08">08</option>
<option value="09">09</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
<option value="13">13</option>
<option value="14">14</option>
<option value="15">15</option>
<option value="16">16</option>
<option value="17">17</option>
<option value="18">18</option>
<option value="19">19</option>
<option value="20">20</option>
<option value="21">21</option>
<option value="22">22</option>
<option value="23">23</option>
<option value="24">24</option>
<option value="25">25</option>
<option value="26">26</option>
<option value="27">27</option>
<option value="28">28</option>
<option value="29">29</option>
<option value="30">30</option>
<option value="31">31</option>
</select>
<select name="checkmonth" value="'. $checkmonth .'">
<option value="01">January</option>
<option value="02">February</option>
<option value="03">March</option>
<option value="04">April</option>
<option value="05">May</option>
<option value="06">June</option>
<option value="07">July</option>
<option value="08">August</option>
<option value="09">September</option>
<option value="10">October</option>
<option value="11">November</option>
<option value="12">December</option>
</select>
<select name="checkyear" value="'. $checkyear .'">
<option value="2001">2001</option>
<option value="2002">2002</option>
<option value="2003">2003</option>
<option value="2004">2004</option>
</select>
<br>
<input type="submit" name="check" value="Check Availability">
</div>
</form>';

?>

file 2 (just for me testing if it works)

<?php
echo"checkday: $checkday<br>";
echo"checkmonth: $checkday<br>";
echo"checkday: $checkyear<br>";

?>

If you want to know how it works let me know.
Good luck.

Yes , as Eelco tells you, you don't need
sessions to do that;

For transmitting data (variables)
between two forms, you can use :

sessions, so you don't need to pass
them in the URL
transmitting data in the URL, so you
don't need sessions

It's two schools for doing the same thing.
(of course there are differences but that's
another story)

It worked great! Wonderful thanks.
Do you know if it would be possible to do it with out using PHP_SELF? Trouble is, its part of a larger page, and i'm not sure if i can refresh the page!
If not i can probably work around it!
Cheers

you can adjust the if statment i put at the beginning of the 'form' file ->
if($check){
echo"<script>window.open('check.php?checkday=$checkday&checkmonth=$checkmonth&checkyear=$checkyear.', 'winname', 'width=300,height=100,scrollbars=no,menubar=no,location=no,status=no,resizable=no,toolbars=no');</script>";
}
else{
rest of the code
}

Now when the main php file is run for the first time $check is not yet set so it wil run the code in the 'else' part, wich also includes the form.
The second time the file is run because of the submission of the form. Now $check is set because the submit button it's name is check and you specified a value for it.
So now only the window opening part is run.

If you don't want to reload the same main file anyway, you can submit the form to another file and do the window opening part there.
