updating a multi value list field from an external form

Hi Jerry.

Here's an example of what I've used for this in the past

$checkboxString = "";
foreach ($_REQUEST[$field['name']] as $value) {
     $checkboxString .= $value ."\t";
}

$colsToValue[ FIELDNAME ] = $checkboxString;

Let me know if that helps.

Thanks!

$checkboxString = "";

Hi Ross,

Hope you'll have a moment to look at this again.

In my haste I seen to have left out the form part of the code I'm trying to use.

In the form, for a list field called ‘levels_of_care’ that gets it’s values from the num field in another table and it’s labels from the title field in that same table, I’m using:

<tr>
              <td valign="top">Levels of Care</td>
              <td><?php $fieldname = 'levels_of_care'; ?>
                <?php
if(is_array(@$_REQUEST[$fieldname])){
$fieldValues = $_REQUEST[$fieldname];
}
else{
$fieldValues = explode("\t",trim(@$_REQUEST[$fieldname],"\t"));
}
?>
                <?php $idCounter = 0; ?>
                <?php foreach (getListOptions('accounts', $fieldname) as $value => $label): ?>
                <?php $id = "$fieldname." . ++$idCounter; ?>
                <input type="checkbox" name="<?php echo $fieldname ?>" id="<?php echo $id ?>"
value="<?php echo htmlspecialchars($value) ?>" <?php if(in_array($value,$fieldValues)):?> checked="checked" <?php endif ?>/>
                <label for="<?php echo $id ?>"><?php echo htmlspecialchars($label) ?></label>
                <br/>
                <?php endforeach ?></td>
            </tr>

When I used:

$colsToValues['levels_of_care'] = "\t" . implode("\t", $_REQUEST['levels_of_care']) . "\t";

To update the levels_of_care database in the colsToValues array, it doesn’t seem to work correctly.

Other fields are updated, but the all multi value list entry check boxes  are cleared and the following error is displayed along with The “Thanks, we've updated your profile!” message:

Warning: implode(): Invalid arguments passed in /home7/ellescho/public_html/dbtct/profile_test3.php on line 55

Using what I think you meant in your suggestion, I replaced the code in the colToValues array with:

 $checkboxString = "";
foreach ($_REQUEST['levels_of_care'] as $value) {
     $checkboxString .= $value ."\t";
}
$colsToValue['levels_of_care'] = $checkboxString;

but that throws the error:

Warning: Invalid argument supplied for foreach() in /home7/ellescho/public_html/dbtct/profile_test4.php on line 56

Sorry for the confusion.

Hi Jerry

I think what might be happening is this variable isn't correct: $_REQUEST['levels_of_care']

What I recommend is using "showme($_REQUEST)" to get a full list of variables available to $_REQUIEST and see what the field name is you need to work with.

Let me know how you make out.

Thanks!

$_REQUEST['levels_of_care']

Hi Jerry.

There are likely a couple things happening here. First, the field in your form needs to have square brackets in it like this:

"name=levels_of_care[]"

Next up, are you saying you weren't expecting numbers to be the value? Or was that part ok?

Let me know how you make out.

Thanks!

Thanks Ross,

The [] (in red) seems to have done the trick. ( do the brackets turn the values into an array?)

For anyone else following this thread, the final code in the form is:

<tr>
              <td valign="top">Levels of Care</td>
              <td><?php $fieldname = 'levels_of_care'; ?>
               <?php
if(is_array(@$_REQUEST[$fieldname])){
$fieldValues = $_REQUEST[$fieldname];
}
else{
$fieldValues = explode("\t",trim(@$_REQUEST[$fieldname],"\t"));
}
?>
                <?php $idCounter = 0; ?>
                <?php foreach (getListOptions('accounts', $fieldname) as $value => $label): ?>
                <?php $id = "$fieldname." . ++$idCounter; ?>
                <input type="checkbox" name="<?php echo $fieldname ?>[]" id="<?php echo $id ?>"
value="<?php echo htmlspecialchars($value) ?>" <?php if(in_array($value,$fieldValues)):?> checked="checked" <?php endif ?>/>
                <label for="<?php echo $id ?>"><?php echo htmlspecialchars($label) ?></label>
                
                <br/>
                <?php endforeach ?></td>
            </tr>

And in the colsToValues array:

  $colsToValues['levels_of_care'] = "\t" . implode("\t", $_REQUEST['levels_of_care']) . "\t";

Note that in this case I'm pulling the list of possible option values (num) and option labels (text) for the levels_of_care field from another table

Best,
