Get POST data from multiple checkboxes?

Im trying to create a form using PHP and I cant seem to find a tutorial on what I need so thought Id ask on here.

I have a multiple checkbox option on my page...

 <li>
    <label>What service are you enquiring about?</label>
    <input type="checkbox" value="Static guarding" name="service">Static guarding<br>
    <input type="checkbox" value="Mobile Patrols" name="service">Mobile Patrols<br>
    <input type="checkbox" value="Alarm response escorting" name="service">Alarm response escorting<br>
    <input type="checkbox" value="Alarm response/ Keyholding" name="service">Alarm response/ Keyholding<br>
    <input type="checkbox" value="Other" name="service">Other<input type="hidden" value="Other" name="service"></span>
  </li>

I'm not sure however how to collect all checkbox values using POST method?

if i use

$service = $_POS开发者_JS百科T['service'];

I only get 'other' returned

Name the fields like service[] instead of service, then you'll be able to access it as array. After that, you can apply regular functions to arrays:

• Check if a certain value was selected:

   if (in_array("Other", $_POST['service'])) { /* Other was selected */}
  

• Get a single newline-separated string with all selected options:

   echo implode("\n", $_POST['service']);
  

• Loop through all selected checkboxes:

   foreach ($_POST['service'] as $service) {
       echo "You selected: $service <br>";
   }
  

Currently it's just catching your last hidden input. Why do you have that hidden input there at all? If you want to gather information if the "Other" box is checked, then you have to hide the

<input type="text" name="other" style="display:none;"/> 

and you can show it with javascript when the "Other" box is checked. Something like that.

Just make the name attribute service[]

<li>
<label>What service are you enquiring about?</label>
<input type="checkbox" value="Static guarding" name="service[]">Static guarding<br />
<input type="checkbox" value="Mobile Patrols" name="service[]">Mobile Patrols<br />
<input type="checkbox" value="Alarm response escorting" name="service[]">Alarm response escorting<br />
<input type="checkbox" value="Alarm response/ Keyholding" name="service[]">Alarm response/ Keyholding<br />
<input type="checkbox" value="Other" name="service[]">Other</span>
</li>

Then in your PHP you can access it like so

$service = $_POST['service'];
echo $service[0]; // Output will be the value of the first selected checkbox
echo $service[1]; // Output will be the value of the second selected checkbox
print_r($service); //Output will be an array of values of the selected checkboxes

etc...

<input type="checkbox" value="Other" name="service">Other<input type="hidden" value="Other" name="service"></span>

You've got a hidden input field with the same name as the checkbox. "later" fields with the same name as an earlier one will overwrite the previous field's values. This means that your form, as posted above, will ALWAYS submit service=Other.

Given the phrasing of your question in the html, it sounds more like you'd want a radio button, which allows only ONE of a group of same-name fields to be selected. Checkboxes are an "AND" situation, radio buttons correspond to "OR"
