How can I fill out a form from the address field of my browser?
http://someform.php/fill out actionfield in form

What I want with this is to fill in this:

<input method="post" action="the input from addresfield of the browser">

This is if I want to use the same form but redigert anser to different e-mails. Why because we are several teachers using the same form and we use a QR code to get to the form, but we need to sort out which teacher instead of redirecting to the right one.

You can use querystrings to achieve that. By the look of it, you have a PHP form. PHP has the $_GET superglobal to access anything from the querystring.

For example, you could link the form to: http://example.com/someform.php?action=add.php. Then in your form code you can do:

<form method="post" action="<?php echo $_GET['action']; ?>">

That way, whatever value you set in the ?action= bit of the URL will be set as the form action.

  • Thanks for fast reply. I was a bit in a hurry when I asked. My form is in a html document so I tried this: http://index3.html?action=contactengine.php And I changed my
    "> Will this still be correct?

if you develope with pure javascript i will give you some tricks about it. i think first you can read this:

How to get the value from the URL parameter?

then read this:

How to set form action through JavaScript?

Now you have some idea about your question. If you can not merge these issues, i give you an example.

.
.
.
<script type="text/javascript">
var QueryString = function () {
  // This function is anonymous, is executed immediately and 
  // the return value is assigned to QueryString!
  var query_string = {};
  var query = window.location.search.substring(1);
  var vars = query.split("&");
  for (var i=0;i<vars.length;i++) {
    var pair = vars[i].split("=");
        // If first entry with this name
    if (typeof query_string[pair[0]] === "undefined") {
      query_string[pair[0]] = pair[1];
        // If second entry with this name
    } else if (typeof query_string[pair[0]] === "string") {
      var arr = [ query_string[pair[0]], pair[1] ];
      query_string[pair[0]] = arr;
        // If third or later entry with this name
    } else {
      query_string[pair[0]].push(pair[1]);
    }
  } 
    return query_string;
} ();
</script>
.
.
.
<script type="text/javascript">
//to set form's action
    window.onload = function() {
        document.myform.action = QueryString['action'];
    }

</script>
.
.
.
<script>
//to see the effect
document.write(QueryString.action);
</script>
.
.
.
<form method="post" name="myform">
<input type="submit" value="Submit">
</form>
.

I did like your solution, but when I tried it it didn't work. I get this answer "The requested URL /dentrafikkskolen/< was not found on this server." And in the address bar it says: 

    http://my_site/dentrafikkskolen/%3C?php%20echo%20$_GET[%27action%27];%20?%3E
I did put the "form metod="post" action=?php echo $_get['action']; ?" in the html site.

This is how the setup is: The for is inside a html site wich is sendt to contactengine.php that sends the e-mail and redirect to a thanks.php site.

<pre>
<form method="post" action="<?php echo $_GET['action']; ?>">
<fieldset>
<legend><span class="number">1</span>Info om deg</legend>
<input type="text" name="Name" placeholder="Ditt Navn *">
<input type="text" name="Mobil" placeholder="Ditt Mobil nummer *">
<input type="text" name="Dob" placeholder="Din Fødselsdag *">
<legend><span class="number">2</span>Ditt valg</legend>
<label for="valg">Hva ønsker du å ta:</label>
<select id="TofD" name="TofD">
<optgroup label="Førerkort:">
<option value="Moped" data-image="icon/moped.png">Moped</option>
<option value="Bil" dat-image="icon/bil.png">Bil</option>
<option value="B96">B96 Tilhenger</option> 
<option value="BE">BE Tilhenger</option>
</optgroup>
<optgroup label="Kurs:">
<option value="1hjelp">Førstehjelp</option>
<option value="tgk">Trafikalt grunnkurs</option>
<option value="last">Lastesikring</option>
</optgroup>
</select>      
</fieldset>

<input type="submit" value="Send" />
</form>

Contactengine.php

<?php
header("Content-Type: text/html;charset=UTF-8");
$EmailFrom = "elev@dentrafikkskolen.no";
$EmailTo = "jarle@dentrafikkskolen.no";
$Subject = "Ny elev";
$Name = Trim(stripslashes($_POST['Name'])) ; 
$Mobil = Trim(stripslashes($_POST['Mobil'])); 
$Dob = Trim(stripslashes($_POST['Dob'])); 
$TofD = Trim(stripslashes($_POST['TofD'])); 

// validation
$validationOK=true;
if (!$validationOK) {
print "<meta http-equiv=\"refresh\" content=\"0;URL=error.htm\">";
exit;
}

// prepare email body text
$Body = "";
$Body .= "Navn: ";
$Body .= $Name;
$Body .= "\n";
$Body .= "Mobil: ";
$Body .= $Mobil;
$Body .= "\n";
$Body .= "Fødselsdag: ";
$Body .= $Dob;
$Body .= "\n";
$Body .= "Eleven har valgt: ";
$Body .= $TofD;
$Body .= "\n";

// send email 
$success = mail($EmailTo, $Subject, $Body, "Fra: <$EmailFrom>\r\nContent-    Type: text/plain; charset=UTF-8\r\nContent-Transfer-Encoding: 8bit");

// redirect to success page 
if ($success){
print "<meta http-equiv=\"refresh\" content=\"0;URL=contactthanks.php\">";
}
else{
print "<meta http-equiv=\"refresh\" content=\"0;URL=error2.htm\">";
}
?>
