[SOLVED] option value remeber

[TD]

Hi, could please someone help me out, i'm thinking how to do this for about a day, and can't solve the prob.

 

When a user clicks on a car the option box selects what car has been choosed, after filling the form in and if he has forgotten to type some info, the script echos what did he forget, and the prob is, that the option value disappears.

How can i save the value or post it over?

 

Thanks ! P.S. sorry for my bad lang.

 

<?php

$t1=$_GET['t1'];

 

switch($t1)

{

case "1":

$t1v="selected='selected'";

$t2v="";

$t3v="";

break;

 

case "2":

$t1v="";

$t2v="selected='selected'";

$t3v="";

break;

 

case "3":

$t1v="";

$t2v="";

$t3v="selected='selected'";

break;

 

}

<form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post">

<select name="auto">

<option value="Polo 1.4i" title="Polo 1.4i" <? echo $t1v?>>Polo 1.4i</option>

<option value="Golf 1.6i" title="Golf 1.6i" <? echo $t2v?>>Golf 1.6i</option>

<option value="Golf 1.9 TDI" title="Golf 1.9 TDI" <? echo $t3v?>>Golf 1.9 TDI</option>

</select>

</form>

Put the value in a session or cookie.  That way you can remember the value and do this:

 

if ($_SESSION['myVal']==1)

$tv1="selected";

 

and so on.

ok will try now, thx.

[DeadEvil]

<?php

 

if($_GET['t1'] = "Polo 1.4i")  $isSelected  = "selected='selected'";

if($_GET['t1'] = "Golf 1.6i") $isSelected2 = "selected='selected'";

if($_GET['t1'] = "Golf 1.9 TDI") $isSelected3 = "selected='selected'";

 

?>

 

 

<form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post">

<select name="auto">

<option value="Polo 1.4i" title="Polo 1.4i" <?=$isSelected?>>Polo 1.4i</option>

<option value="Golf 1.6i" title="Golf 1.6i" <?=$isSelected2?>>Golf 1.6i</option>

<option value="Golf 1.9 TDI" title="Golf 1.9 TDI" <?=$isSelected3?>>Golf 1.9 TDI</option>

</select>

</form>

[TD]

wow it works, big thx DeadEvil, many many thanks. 

[DeadEvil]

your welcome.

[TD]

xmm i have not correctly tested, because  the option box is always selecting the last option, so something is wrong it just wont remember.

[DeadEvil]

try this one

 

<?

<option value="Polo 1.4i" title="Polo 1.4i" <?=$isSelected?><? unset($isSelected) ?>>Polo 1.4i</option>

<option value="Golf 1.6i" title="Golf 1.6i" <?=$isSelected2?><? unset($isSelected2']) ?>>Golf 1.6i</option>

<option value="Golf 1.9 TDI" title="Golf 1.9 TDI" <?=$isSelected3?><? unset($isSelected3) ?>>Golf 1.9 TDI</option>

?>

[TD]

no reaction, the same..  ???

[DeadEvil]

Error in operation I think "if($_GET['t1'] = "Polo 1.4i")"

 

<?php

 

if($_GET['t1'] == "Polo 1.4i")    $isSelected = "selected='selected'";

if($_GET['t1'] == "Golf 1.6i")    $isSelected2 = "selected='selected'";

if($_GET['t1'] == "Golf 1.9 TDI") $isSelected3 = "selected='selected'";

 

?>

 

 

<form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post">

<select name="auto">

<option value="Polo 1.4i" title="Polo 1.4i" <?=$isSelected?>>Polo 1.4i</option>

<option value="Golf 1.6i" title="Golf 1.6i" <?=$isSelected2?>>Golf 1.6i</option>

<option value="Golf 1.9 TDI" title="Golf 1.9 TDI" <?=$isSelected3?>>Golf 1.9 TDI</option>

</select>

</form>

[phpknight]

You don't need the 'selected=' part.  Just put SELECTED for the one you want.

[TD]

allright the code looks now so and the option values work, but it just wont remember, when i hit submit form.

 

if($_GET['t1'] == "Polo 1.4i")      $isSelected  = "selected";

if($_GET['t1'] == "Golf 1.6i")    $isSelected2 = "selected";

if($_GET['t1'] == "Golf 1.9 TDI") $isSelected3 = "selected";

 

 

<option value="Polo 1.4i" title="Polo 1.4i" <?=$isSelected?>>Polo 1.4i</option>

<option value="Golf 1.6i" title="Golf 1.6i" <?=$isSelected2?>>Golf 1.6i</option>

<option value="Golf 1.9 TDI" title="Golf 1.9 TDI" <?=$isSelected3?>>Golf 1.9 TDI</option>

[phpknight]

Like I said before, use a SESSION or  COOKIE.  Did you try that?  HTML is a stateless protocol, so you have to make it remember something.

 

session_start(); //on very top of script for both scripts if separate

 

 

//on verification part

$_SESSION['myValue']=1; //1, 2, or 3

 

 

if ($_SESSION['myValue'])==1)

print "SELECTED";

//do the same for 2 or 3

 

Does that make sense?

 

[TD]

well i'm not familiar to sessions, could you please make a little sample for one car. Thanks!

[phpknight]

Could you give me the URL to this?  That would be quicker.

 

Also, send me the entire code for the page(s) so I can test it on my server and give you working code.

[TD]

http://www.racing.lv/car/

 

You can easy simulate the buttons self

http://www.racing.lv/car/reg.php?t1=Golf%201.6i

And after hit submit you will see that it just dont work.

 

You need reg.php and form.php

 

[phpknight]

Am I missing something?  If I click a choice, get the errors, and then click back, the option I chose is always highlighted in the drop-down box.  I tested it twice for all of them.  That is exactly what you want, right?

 

I think it is the printed line under that you just forgot to change.

[TD]

Well yes with the back button it works, but mostly users just change immediatly all the form, they dont hit back, and if it's so, then the car vanishes and selects the first one.

[phpknight]

Oh, I see.  I didn't actually wait that long to see the new form.

 

First, I need the actual code because the PHP is of no use already having been executed on the server.

 

Two ideas:  1. Just separate the form and the results. or

2. I can try to fix it, lol!

[TD]

Well i just thinked about your 1 idea, yes thats a option, but maybe if you get it really quick, without prob. then the 2 option would be much better. I would very appreciate it. Thanks for helping!

The code you can easy save with save target as.. http://www.racing.lv/car/

[phpknight]

Okay, give me a few minutes.

[TD]

will try

[adam_]

make sure the if's have ==, not just =, otherwise they return always true

[phpknight]

This has changed the values to 1, 2, and 3, but this solves the specific problem I think.

 

Forgive me for not using a switch.  For some reason, I don't like them, lol.

 

Let me know if it works.
