Hallo,

Ik ben bezig met een formulier waar radio buttons in staan die gevalideerd worden. Echter als je 1 van hen aanvinkt en op "Verstuur" drukt dan verliest hij de gekozen waarde. zie: http://www.rc-maps.com/modelbouwtest/contact-test.php

Kan iemand mij hiermee helpen?

2de vraag: Wat doen die stripslashes eigenlijk?

Hier mijn code:

Hey Milcoi,


Stripslashes is handig wanneer je escaped kakakters weer wilt escapen :)
Bij sql insert moet je deze namelijk escapen
hoe werkt dit functie:dit heb je \' -> strip slash dit maakt het-> '
ps php.net aanrader!

Je form verlies waarde... mmm.. als ik je code bekijk zie ik dat je voor de variables namen laadt, je test eerst of form verzonden is! dat is op zich normaal, maar op dat punt wijs je de variablen toe.
<input type= text value="
Code (php)
PHP script in nieuw venster Selecteer het PHP script
1
<? echo $var?>
">
verschilt met
<input type= text value="
Code (php)
PHP script in nieuw venster Selecteer het PHP script
1
<? echo $_POST['name']?>
">


Ik denk dat dit je probleem ook oplost.

Nee dit zal het probleem niet oplossen.
Dit gaat over radio-buttons.
een voorbeeldje, we gaan ervan uit dat je Alkmaar standaard geselecteerd wilt hebben:

Code (php)

<?php
$locationValue = '072';
if(isset($_POST['location'])) {
    $locationValue = strip_slashes($_POST['location']);
}
?>
<input type="radio" name="location" value="072"<?php echo $locationValue == '072' ? ' checked="checked"' : ''; ?> /> Alkmaar
<input type="radio" name="location" value="020"<?php echo $locationValue == '020' ? ' checked="checked"' : ''; ?> /> Amsterdam
<input type="radio" name="location" value="030"<?php echo $locationValue == '030' ? ' checked="checked"' : ''; ?> /> Utrecht


Volgens mij moet je er zo wel uitkomen... zoniet horen we het weer!

Mijns inziens de mooiste manier:

bijvoorbeeld:

Code (php)
PHP script in nieuw venster Selecteer het PHP script
1
<input type="radio" name="name" value="value" <?PHP if(isset($_POST["name"]) and $_POST["name"]==value) {ECHO "\"checked\" />";}?>

Niet Bumpen::
Twee of meer keer achter elkaar in een topic posten heet bumpen. Bumpen is pas na 24 uur toegestaan en kan een reden zijn voor de admins en moderators om een topic te sluiten. Gebruik indien nodig de Afbeelding knop om je tekst aan te passen.
