Dynamic form

[beanieboy]

Hi,

 

I have a timetable search form which lets you search for travel options after a time.

 

i.e. search for the next three buses after 3pm to manchester

 

I have a basic html form which submits a post to a php file.

 

 

The php file takes the postfields and outputs to screen three variables $time1 , $time2 & $time3 . These output three times in 24 hour format. i.e.

 

12:30

13:45

02:02

 

What i want to do is basically when i click submit on the previous form, create the same form with the previous details still selected, but with an extra select list with the $time# values in them.

 

Can this be done, i'm not sure how to

 

Thanks

Hi

 

Yes. Would be pretty easy to do. Just take the values from the $_POST array and put them as values for the input fields when you put the screen out again. The put the time periods out like:-

 

<select name="timeperiod">
<option value="12:30">12:30</option>
<option value="13:45">13:45</option>
<option value="02:02">02:02</option>
</select>

 

All the best

ok not sure how i would do that with the way i have my form setup.

 

here's my code below.

 

the php file - scrapes a file from a site using curl and then finds then get the times andd puts them into variables $time1 $time2 $time3.

 

how do i post these back to search.html, or should i create a new form ?

 

 

***heres my html form (search.html) ***

 

<form action="formdatanew.php" method="post" name="SearchTicket" id="SearchTicket">

  <select name="from.searchTerm" id="from">

                <option value="Abbey Wood">Abbey Wood</option>

                <option value="Aber">Aber</option>

                <option value="Abercynon North">Abercynon North</option>

            </select> 

 

              <select name="timeOfOutwardJourney.day" id="depDayDrop">

                <option value="01" selected="selected">1</option>

                <option value="02">2</option>

                <option value="03">3</option>

              </select>

<input type="submit" name="Submit" value="Submit" />

</form>

Hi

 

Crude and fast rewrite:-

 

<?php 
//*** PHP Form formdatanew.php ***

if (isset($_POST['from_searchTerm']) AND isset($_POST['timeOfOutwardJourney_day']) AND !isset($_POST['newtimefield'])
{

$str2rail = "from.searchTerm=" . $_POST['from_searchTerm'] . "&timeOfOutwardJourney.day=" . $_POST['timeOfOutwardJourney_day'] . "&planjourney=SEARCH";
$URL="http://test3/search"; 

$ch = curl_init();    
curl_setopt($ch, CURLOPT_URL,"$URL"); 
curl_setopt($ch, CURLOPT_COOKIE, $matches[1]); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $str2rail); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // added is needed? 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 

$times = curl_exec($ch);
$cut = explode(" ", $times); 
$count=count($cut);
$stringse = "singleCellwidth\"";
$stringse2 = ">";
$stringse3 = ":";

$depcount=0;
$dep1="";
$dep2="";
$dep3="";

for($i=0;$i<$count;$i++)
 {
   if (strstr($cut[$i],$stringse) == TRUE)
   {
       $cut[$i] = ereg_replace( $stringse, "", $cut[$i] );
       $cut[$i] = ereg_replace( $stringse2, "", $cut[$i] );
       
      if ($depcount < 4) 
      {
       if (strstr($cut[$i],$stringse3   ) == TRUE) 
       {   
         $dep[$depcount]=$cut[$i];
          print ($dep[$depcount]);
          print "<br />";print "<br />";
         $depcount=$depcount+1;
       }
        }
   }
 }
curl_close ($ch);
displayPage($_POST['from_searchTerm'], $_POST['timeOfOutwardJourney_day'], array($time1,$time2,$time3));
}
else
{
displayPage($_POST['from_searchTerm'], $_POST['timeOfOutwardJourney_day']);
}
function displayPage($from_searchTerm = "", $timeOfOutwardJourney_day = "", $newtimefield = array())
{
?>
<form action="formdatanew.php" method="post" name="SearchTicket" id="SearchTicket">   
      <select name="from.searchTerm" id="from">
                <option value="Abbey Wood" <?php echo (($from_searchTerm == "Abbey Wood") ? "selected='selected'" : ""); ?>>Abbey Wood</option>
                <option value="Aber" <?php echo (($from_searchTerm == "Aber") ? "selected='selected'" : ""); ?>>Aber</option>
                <option value="Abercynon North" <?php echo (($from_searchTerm == "Abercynon North") ? "selected='selected'" : ""); ?>>Abercynon North</option>
             </select>  

              <select name="timeOfOutwardJourney.day" id="depDayDrop">
                <option value="01" <?php echo (($timeOfOutwardJourney_day == "01") ? "selected='selected'" : ""); ?>>1</option>
                <option value="02" <?php echo (($timeOfOutwardJourney_day == "02") ? "selected='selected'" : ""); ?>>2</option>
                <option value="03" <?php echo (($timeOfOutwardJourney_day == "03") ? "selected='selected'" : ""); ?>>3</option>
              </select> 
<?php
if (count($newtimefield) > 0)
{
    echo "<select name='newtimefield' id='newtimefield'>";
foreach ($newtimefield as $value)
{
	echo "<option value='$value' >$value</option>";
}
echo "</select>";
}

?>
                        <input type="submit" name="Submit" value="Submit" /> 
</form>
<?php
}
?>

 

Think that is the kind of thing you want (although cannot see where you assign $time1, $time2 & $time3).

 

Note that just putting your $_POST fields into the SQL is not advisable.

 

All the best

thanks i'll give a go.

 

sorry had a brainfart.  i store the values in $dep# not $time#

 

will let you know. many thanks for your help so far as i'm not a php coder, just someone whos been landed in it

Hi

 

That makes it easier. The function is expecting an array there, so you can just pass the array $dep.

 

All the best
