parameter from URL via `$_REQUEST` into hidden fields

  • Hello!

    I tried this code within the form but it just generates code which can be seen in the source (but has no effect as such):

    <?php while (list ($key, $value) = each ($_REQUEST))
    {
        echo "<input type='hidden' name='".htmlspecialchars($key)."' value='".htmlspecialchars($value)."'>";
    }?>

    After searching for quite a while I found no plugin for my problem: I want to show all parameters provided via the URL in hidden fields in the form (without knowing how many of them are there and what there names are).

    Is there a way to do so without changing to much of the original code? Is there an “easy way”?

    Thank you for your help in advance.

  • cf7 forms only supports HTML.
    If you want to use PHP, you probably have to create a template file.

    Thank you for your answer!

    How can I use a template file with cf7? I create a php file called list-param.php with my code and then?

    Or can I use JavaScript? I am just not sure if JavaScript can do the same as php can…and how the code would have to look like.

    In a php file make sure it begins with

    <?php /*Template Name: xxx*/

    Then when you’re at a page you can select the template.

    I don’t think you can do anything with the URL using JavaScript, because only PHP is server side.

    Well, I can always use

    <script type="text/javascript">
<!--
var params = {};
if (location.search) {
    var parts = location.search.substring(1).split('&');

    for (var i = 0; i < parts.length; i++) {
        var nv = parts[i].split('=');
        if (!nv[0]) continue;
        params[nv[0]] = nv[1] || true;
    }
}
var keyword = params.keyword;
alert(keyword);
//--></script>

    And then somehow try to get the values by id or whatever into the code…but that is not what I would like. Maybe someone else has an idea?

    thank you for the information…as there was an answer but the problem could not be solved with that answer it does not really qualify for “bumping” as it deals only with posts that did not receive any answers at all. Therefore it would be helpful if people would only post real answers related to the topic.

    Actually I can’t believe that I am the only one who wants to read out parameters sent via GET with the URL and add it into hidden fields into a form. Of course I can use a plugin and manually add all keys but that is not a comfortable solution.

    <?php while (list ($key, $value) = each ($_REQUEST))
    {
        echo "<input type='hidden' name='".htmlspecialchars($key)."' value='".htmlspecialchars($value)."'>";
    }?>

    I just want these few lines of code in the form…is there anyone who has an idea how to get them inside a cf7-form?
