How to submit multiple checkbox values? - php

Question

I want to have multiple values for checkboxes. How do I do that?
It only adds the first option that is selected
<input type="checkbox" name="fields[options]" value="option1[]">option1
<input type="checkbox" name="fields[options]" value="option2[]">option2
<input type="checkbox" name="fields[options]" value="option3[]">option3
There are two PHP files. I will post them below. I am not that experienced with php.
/**************** GOOGLE.DOCS method ************************/
if($_SETTINGS['store_to_gdocs'])
{
include_once("GoogleSpreadsheet/Google_Spreadsheet.php");
$ss = new Google_Spreadsheet($_SETTINGS['gdocs']['user'],$_SETTINGS['gdocs']['password']);
$ss->useSpreadsheet($_SETTINGS['gdocs']['spreadsheet_name']);
$ss->useWorksheet($_SETTINGS['gdocs']['worksheet_name']);
$row = array
(
"Date" => date("m/d/Y H:i"),
);
foreach($_POST['fields'] as $k=>$v)
$row[$k]=$v;
if(!$ss->addRow($row))
$ret['error']=1;
}
Second file

Thank you for helping!

Answer 1

You have your checkbox names and values mixed up. It should be:
<input type="checkbox" name="fields[options][]" value="option1">option1
<input type="checkbox" name="fields[options][]" value="option2">option2
<input type="checkbox" name="fields[options][]" value="option3">option3
Now you can manipulate $_POST['fields']['options'] like so:
$options = (is_array($_POST['fields']['options'])) ? $_POST['fields']['options'] : array();
Then you can implode them:
$options_string = implode(',', $options) // will return option1,option2,option3 etc
or loop through them:
foreach ($options as $option)
{
echo $option.'<br>';
}
// produces option1<br>option2<br>option3 etc

Answer 2

Don't give the name a key in the array - it should be set to name="fields[]".
