Hello
I am sorry if my question is stupid but I can not get the value of input of a form

I created a CHUNK and I past a simple form with two input. I add teh CHUNK to my template named 'stage'.

<form class="form-inline" method="get" action="[[~[[*id]]]]">
  <div class="form-group">

    <label for="input_place">Rechercher un stage</label>
    <input type="text" class="form-control" id="input_place" name="input_place" placeholder="Lieux">
  </div>
  <div class="form-group">
    <label for="input_date">ou</label>
    <input type="date" class="form-control datepicker" id="input_date" name="input_date" placeholder="sélectionnez une date">

  </div>
  <button type="submit" class="btn btn-default">Envoyer</button>
</form>
<hr>

I created a resource and I chosed the template 'stage'

Finaly, I created a SNIPPETS and I pasted PHP code. At the begining of my snipppet I psted the following code

foreach($_GET as $k => $r)
{
	echo $k.'=>'.$r.'<br>';
}

When I send my form with some values ("toto" and "titi", the foreach of my snippet do not show me 'toto' and tit' but

cultureKey=>
q=>stages/stage.html

while it should display

inout_place=>toto
input_date=>titi

The is not a MODx class or something else, which let me get the form value?
How can I get the input value from a snippets?

Thank a lot [ed. note: pierrot1010 last edited this post 9 years, 11 months ago.]

It seams to be a cache problem.
Bur now I try to send the form with the post method

I also foud the following


foreach($_POST as $ki => $ri)
{
	echo $ki.' p>'.$ri.'<br>';
}

echo $modx->resource->get('input_place'); echo '<br>';
echo $modx->resource->get('input_date');

Again nothing is showed. I clear the cache and nothing is displayed shocked

I solved my problem.

I called my snippets as the following

[[filterStage? &parents=`14` &date=`2016-11-22` &place=`genev`]]

I added a !

[[!filterStage? &parents=`14` &date=`2016-11-22` &place=`genev`]]

And now each time I send my form, I can display the value with this:

foreach($_POST as $ki => $ri)
{
	echo $ki.' p>'.$ri.'<br>';
}

Now, this was really stupid

//echo $modx->resource->get('input_place'); echo '<br>';

because it look for an element of my resource (which does not exist) and not of my from.

However, this should work

echo $modx->resource->get('id')

But there is something like this, to get the value of an input of my form? (to avoid a foreach loop)

Is this what you're looking for?

$val = $_POST['fieldname'];
