Help with PHP $_POST from a form

[madjack87]

Current I have php create a form element for every entry found in the database that meets certain criteria.

 

On the form submit it submits information about each form element and can be anywhere from 1-20 elements.

 

The issue that I am having is when I try to gather the day from $_POST I do not know how many form elements are being sent over. So I end up typing something like this.

 

$form_element_1 = $_POST['form_element_1'];

$form_element_2 = $_POST['form_element_2'];

$form_element_3 = $_POST['form_element_3'];

 

And I type that out for as many as I think I need. But as soon as I need 4 elements I have to go and recode that page to accept more elements.

 

I hope that I am asking this question properly.

 

Thanks

perhaps count($_POST)

Sometimes its the simplest things that hold me up in coding.

 

didnt even realize that you could count($_POST);

 

I will give this a try and go from there.

 

Thanks

Most likely count() won't work in this instance cause it will include all $_POST elements including the submit button and any other form elements.  The form elements that you are having issue with, are they all the same type of form element and are you processing them all in the same exact manner?  If so then I would suggest using an array for the "name" attribute of the element, this way it will come across in the php in an array and you can run a foreach loop to process them.

<input type="text" name="form_element[]">

// use a print_r($_POST); to see how the elements come across as an array
print_r($_POST);

foreach($_POST['form_element'] as $element)
{ echo $element; }

$ff = "20";


         for($loop=1;$loop<=$ff;$loop++)

         {


echo "<option>".$loop."</option>"; 

}

echo "</select><br>";

?>

<script type="text/javascript" src="XXXXXXXXX"></script>

<input type="submit" value="Send SmS"></form><br> <div style="background:grey;padding:4px;color:white" align="center">© XXXXX</div>
