Call info from one specific custom field

[samborabora]

I have custom profile called 'About Me' and it's code in the profile editor is:

Code Select Expand

<textarea name="customfield[cust_aboutm0]" rows="5" cols="50"></textarea>

I'd like, instead of calling for all of the custom fields together, to call just one custom field, in this case, I assume it is called cust_aboutm0. I tried:

Code Select Expand

   foreach ($context['custom_fields'] as $field)
      {
      if ($field['name'] == 'cust_aboutm0')
         echo '
            <dt>', $field['name'], ':</dt>
            <dd>', $field['output_html'], '</dd>';
      }

But this displays nothing. Where did I go wrong?

whenever i wanna get something from an array and i  have no documentation about it i usually use print_r:

print_r($context['custom_fields']);

then you can get the key/id of the field you want and call it directly without having to iterate throught all its items.

Where are you trying to use that custom field exactly?

Where are you trying to use that custom field exactly?

On the profile, but I don't want to use the standard output of all the custom fields, I want to specify an individual form.

On what profile? The main profile? The mini profile on post view?

On what profile? The main profile? The mini profile on post view?

profile.template.php, the profile of whichever user you click on, every users profile.

Thanks, I tried this and all I got was

Code Select Expand

Array ( [0] => Array ( [name] => About Me [desc] => [type] => textarea [input_html] =>  [output_html] => [placement] => 0 [colname] => cust_aboutm0 [value] => ) [1] => Array ( [name] => Facebook Profile [desc] => Facebook Profile [type] => text [input_html] =>  [output_html] => [placement] => 0 [colname] => face_pro [value] => ) )

Which once again just confirms that name was cust_aboutm0 but I still cant figure how to just show this field?

[ZerK]

there are multiple ways to do this:

Code Select Expand


foreach ($context['custom_fields'] as $field)
if($field[colname] == "cust_aboutm0")
echo $field['value'];

the second one is just printing it:
name:

Code Select Expand

echo $context['custom_fields'][0]['name'];
value:

Code Select Expand

echo $context['custom_fields'][0]['value'];

Perfect, that first one works!  Thanks so much!!

One last question, what's the best way of checking if the value is empty, ie: if the field in question has no text in it, so I can put an "they've said nothing" or whatever message?

EDIT: Pardon my ignorance, but I've tried this, and it doesn't work, but I'm not the best php coder yet!

Code Select Expand

if (!empty($field[colname] == "cust_aboutm0"))

[ZerK]

Code Select Expand

foreach ($context['custom_fields'] as $field)
if($field['colname'] == "cust_aboutm0")
echo (empty($field['value']) ? 'they ve said nothing' : $field['value']);


didnt tested it but it should work.

Perfect, thankyou!!

This was helpful but ¿what about showing the custom field in Display.template.php ?

I tried

Code Select Expand

echo $context['custom_fields']['cust_tipode']['value'];

cust_tipode is the name of the variable of the value I want to get (I'm not sure if works like that).

So I have the table smf_themes with
id_member - id_theme - variable - value
------------------------------------------
5828        -   1      - cust_tipode - valueA
5748        -   1      - cust_tipode - valueB
...
...

(I thought no need to open new thread for the similarity of what I need)

Thanks

Finally found it

(Yo have to add $smcFunc to function template_main in Display.template.php  (line 15))
