How to make the form have the previous values

[amii12]

I have form with input text, input radio and input select fields. User submit form and get results, afterwards he/she clicks the back button in the browser and get empty fields.
I want to make the form have the previous entered values. Any ideas how to do this ?

You will have to use sessions to get the data back, either storing each field in a designated session variable or storing the info in a database with the session_id

You could probably use $_SESSION to remember the values in each field.

SNAP - Optik beat me to it.

Yeah got it, session seems to work on text fields. but what about radio buttons and select options fields ?
This is my piece of code:

$html .= '<td class="inna" colspan="2">			
					<input type="radio" name="zoladek" value="pusty" '.$zolodek1.'>&nbsp;pusty<br>
					<input type="radio" name="zoladek" value="pelny1/2" '.$zolodek2.'>&nbsp;w po&#322;owie pe&#322;ny<br>
					<input type="radio" name="zoladek" value="pelny" '.$zolodek3.'>&nbsp;pe&#322;ny &#380;o&#322;±dek
				</td>';


$html .= '<select name="godzina" id="godzina" class="i1">
					<option value="0">0</option> 
							<option value="1">1</option>
							<option value="2">2</option>
							<option value="3">3</option>
							<option value="4">4</option>
							<option value="5">5</option>
							<option value="6">6</option>
							<option value="7">7</option>
							<option value="8">8</option>
							<option value="9">9</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" selected>20</option>
							<option value="21">21</option>
							<option value="22">22</option>
							<option value="23">23</option>
					</select>';

I try ro resolve this on put this piece of code on the beginning of the form file but doesnt work:

session_start(); 
$zolodek1 = ($_SESSION['zolodek'] == 'pusty' ? 'checked="checked"' : '');
$zolodek2 = ($_SESSION['zolodek'] == 'pelny1/2' ? 'checked="checked"' : '');
$zolodek3 = ($_SESSION['zolodek'] == 'pelny' ? 'checked="checked"' : '');

maybe just checked instead of checked="checked"

Thanks optik it works seem to me that i tried it earlier though nevermind, but I still have problem with select fields

[optik]

Make sure you only have one menu item with "selected" as an attribute it's always the last one on the list that is actually selected.

[amii12]

OK but how to "transport" selected field through the session, any ideas ?

I try:

for($b=0; $b<24; $b++)  {  //loop with options creations, 24 is the numer of options in select field
if ($b==5) $petla .= '<option value="'.$b.'" selected>'.$b.'</option>';
else $petla .= '<option value="'.$b.'">'.$b.'</option>';
}

//some other not important code

$html .= '<select name="czaspicia" id="czaspicia" class="i1">
					'.$petla.'  //options fields form loop

				</select> godziny';

it works for option 5, but what about session if the user click let say 9 and then back to the page i want option 9 selected

Right I see, for menus I always repeat the selected field above the whole list and separate the two parts with a null option of "---------------------------" , you could use javascript but I find this solution works fine.
