Setting links for multibox values

*Update:

So I found the ‘Adding an Edit Record Link to the Frontend List’ and thought perhaps it would also be possible with this.

So I followed the tutorial and created the link, though this tutorial (and code) doesn’t seem to work on multiselect boxes and their values.. And though, if it worked it still needed some kind of if statement to look which of the multiselect options was chosen (if option 1 was chosen –> then insert a link to website/page A and if option 2 was chosen –> then insert a link to website/page B

You’re on the right track, it will probably require that you take the field value, which will be a string with commas, and break it up into substrings. Then for each substring, you can attach your link. Reassemble the whole thing and display it.

Thanks for your reply!

Though, I am getting stuck as all the things I tried aren’t working.

I am working with this piece of code:

<?php $record = new PDb_Template($this); ?>
  <tr>
    <?php while( $this->have_fields() ) : $this->the_field(); // each field is one cell ?>
      <td class="<?php echo $this->field->name ?>-field">
        <?php
        /*
         * put the edit link URL into the link property of the field
         */
        if ($this->field->name == 'edit_link') {
          $this->field->link = $record->get_edit_link(https://testing-purposes.com/);
        }
        $this->field->print_value();
        ?>
      </td>

I tried to work with the ‘values’, use the && to select it, etc. But still it all doesn’t work, probably because I am way off (lacking the know how). Could you point me a bit in the right direction? For example: how do I target the values in the field? Or how do I assign the link to that values? Just need a bit coding direction. (BTw I kept using edit_link for testing purposes).

Thank you in advance!

OK, because your field is one that can contain multiple values, you have to take a very different approach to creating your links. You can’t use “values” because those are the preset values of the field and not what is stored in the database for the record.

The critical part of this code that I have no idea how to do is mapping the values to the links, so I’ll just put in a generic mapping function, you should be able to go from there on that.

Let’s say your field is named “links”…

<?php
function value_link($value) {
  $map = array(
    'value 1' => 'https://link_1.com',
    'value 2' => '/page-slug'
  );
  return $map[$value];
}

if ($this->field->name === 'links') {
  $output = '';
  $value_array = explode(',', $this->field->value);
  foreach ($value_array as $the_value) {
    $the_value = trim($the_value); // in case there are spaces
    $output .= '<a href="' . value_link($the_value) . '">' . $the_value . '</a> ';
  }
  echo $output;
} else {
  $this->field->print_value();
}
?>

That should get you started. Watch out for errors in my code… I just banged that out.

Dear xnau,

Thank you for your fast replies and your answer!

So I’ll give you an status update. I try’d to go from the point of your piece of code. I had several error messages which I ficed. With the fixes in place the code now looks like:

<?php
if(!function_exists("value_link")) {     //First error message was here that the function already existed so I included the !function_exists
function value_link($value) {
  $map = array(
    'Yes' => 'https://www.google.com',
    'No' => 'https://www.hotmail.com'
  );
  return $map[$value];
}
}

if ($this->field->name === 'edit_link') {
  $output = '';
  $value_array = explode(',', (string) $this->field->value); //Second error here, had to insert the string because object to string wasn't possible)
  foreach ((array)$value_array as $the_value) {
    $the_value = trim($the_value); // in case there are spaces
    $output .= '<a href="' . value_link($the_value) . '">' . $the_value . '</a> ';
  }
  echo $output;
} else {
  $this->field->print_value();
}
?>

So when I ran this piece of code, the links still wouldn’t work.. IN all the examples (one multiselect stored as well as both stored) gives still the word: Array in return. This Array word does have a link though, but when I click this link it returns me to the page I was on already. Besides that, for the stored example of two multiselect options, it still return only ONE Array word (instead of two).

Thanks in advance!

Yeah, I should have told you to put the function declaration at the top of the template so it wouldn’t get redeclared. So you can do that and unwrap it from the function_exists call.

Huh, well what you’ve got for your map doesn’t make sense, it seems to imply you expect them to choose one or the other, not both….so why do you need a multiselect?

Anyway, if you really do need a multiselect, I led you astray. $this->field_>value will already be an array, so there’s no need to explode it. So, take that line out completely, and just use $this->field->value as the first term in your foreach and you’ll be good.

No need to use the type casting declarations, they’re just masking useful information about your variables, so it’s good to avoid using them most of the time. If it gives an error, look at your code to see why you’re getting the wrong type. It will make you a better coder.

xnau,

It works like a charm! Many thanks.

As i see a lot of people in posts looking for the same i’ll post the code with a step-based to-do’s in here for this functionality.

So this is for creating multibox fields and attach links to the options:

1. create a custom template based on pdb-list
2. insert the function code on top of the page:

function value_link($value) {
  $map = array(
    'Yes' => 'https://www.google.nl',
    'No' => 'https://www.hotmail.com'
    'Something else' => 'https://www.something.com'
  );
  return $map[$value];
}

3. insert the following code between the tbody:

<?php while ( $this->have_records() ) : $this->the_record(); // each record is one row ?>
    <?php $record = new PDb_Template($this); ?>
  <tr>
    <?php while( $this->have_fields() ) : $this->the_field(); // each field is one cell ?>
      <td class="<?php echo $this->field->name ?>-field">
        <?php

if ($this->field->name === 'edit_link') {
  $output = '';

  foreach ($this->field->value as $the_value) {

    $the_value = trim($the_value); // in case there are spaces
    $output .= '<a href="' . value_link($the_value) . '">' . $the_value . '</a> ';
  }
  echo $output;
} else {
  $this->field->print_value();
}
?>
      </td>
  <?php endwhile; // each field ?>
  </tr>
<?php endwhile; // each record ?>

4. Change the fields to your fields (so field is called here edit_link but this should be named to your own created multibox field.

Anyway, thanks a lot xnau!

excellent.
