[FX.php List] 2 value Lists together help

[Steve Winter]

Opps... just spotted a typo there, and that font has done weird things to
the ‘ and “ try this;

 

First code block from below should be

 

$contacts = array();

foreach($contactAreas['data'] as $contact)

  array_push($contacts, $contact[‘area’][0]);

 

foreach($VLAreas['data'] as $area) {

  echo '<p><input type="checkbox" name="contact[]" value="'.$area.'"';

  if(in_array($area,$contacts)) echo ' checked="checked"';

  echo '>'.$area.'</p>';

}

 

Second code block, for the receiving page;

 

$contacts = array();

foreach($contactAreas['data'] as $key => $contact)

  $contacts[$key] = $contact['area'][0];

 

foreach($_REQUEST['area'] as $area) {

  if(!in_array($area,$contacts)) {

    // this means that a new area has been checked

    // create a new record

  }

}

 

foreach($contacts as $contactKey => $contactValue) {

  if(!in_array($contactValue,$_REQUEST['areas'])) {

    // this means that the box has been unchecked

    // so use $contactKey to delete the record

  }

}

Hi William,

 

Okay, I'll play... I think I understand what you want to do, with the first
part of your query, then we’ll see if I get that right, and then I’ll have a
go at the second part...

 

I assume that the values returned by the contactAreas search will be a
subset of the records in the VLAreas table...? If that’s correct, this is
what I’d do...

 

$contacts = array();

foreach($contactAreas[‘data’] as $contact)

  array_push($contacts, $contact[‘area’][0])

 

foreach($VLAreas[‘data’] as $area) {

  echo ‘<p><input type=”checkbox” name=”area[]” value=”’.$area.’”’;

  if(in_array($area,$contacts)) echo ‘ checked=”checked”’;

  echo ‘>’.$item.’</p>’;

 

Which should give you a checkbox for all of the records in VLAreas, with
those checkboxes for which there is a record in contactAreas...

 

Now what you need to do is post the data back to FMP... I’d pass the parent
ID in the form that you send... 

 

When you post the data back to the receiving page you should end up with an
array called contact, which has the values which have been checked in it...

 

What I would then do is re-perform your initial search, and create an array
of the records from contactAreas which has the –recID as the key and the
area as the value, so;

 

$contacts = array();

foreach($contactAreas[‘data’] as $key => $contact)

  $contacts[$key] = $contact[‘area’][0];

 

Then I’d loop through my posted array and see if the record already
exists... if it does, then that’s great, if not add it...

 

foreach($_REQUEST[‘area’] as $area) {

  if(!in_array($area,$contacts)) {

    // this means that a new area has been checked

    // create a new record

  }

}

 

Now you need to do the opposite and find out if any have been unchecked...

 

foreach($contacts as $contactKey => $contactValue) {

  if(!in_array($contactValue,$_REQUEST[‘areas’])) {

    // this means that the box has been unchecked

    // so use $contactKey to delete the record

  }

}

 

Hope this makes sense... not tested, but looks solid to me...

 

Cheers

Steve

Hi Guys,

 

A quick question (OK, I say quick but that word means different things

to different people)

I run the following query on 3 tables in Filemaker.

 

find the Parent record from Contacts table

find any associated child records from ContactAreas table

find ALL records from VLAreas table

Works fine.

 

I need to be able to say in PHP - display a checkbox alongside any of

the records from the VLAreas table (I can do that) and if some of the

values from the ContactAreas table matches any of the values from the

VLAreas table, then let the box be checked (sort of like comparing 2

arrays I think)

 

I then of course have to be able to FMEdit the changes.

 

Does someone already know how to do this ?

 

Many kind thanks in advance

 

William
