    <p>Here is a bit of code that displays: 'varname: varvalue' in a browser. It is used by calling the vc('varname'); or vc(array('multiple','varnames'));</p> <p>I first tried writing: </p> <pre><code>if (gettype($$var_string) == ('string' || 'boolean' || 'integer' || 'double')){} </code></pre> <p>however this didn't work. The second group simplifies to true, and it always passed the conditional check.</p> <p>So, I wrote out each check separately. I'm new to coding, I'm sure there's an easier way, not sure what it would be. I haven't had any luck searching here or google. (probably not using the right jargon). Thanks in advance. - Mike</p> <p>Oh, this is PHP, btw. The problem in question applies to any language thou.</p> <pre><code>define('LB', '&lt;br /&gt;'); $var1 = 5; $var2 = array('mike', 'lewis', 'is', 'awesome'); function vc($var_string) { if (!is_array($var_string)){ $var_string = array($var_string); } foreach ($var_string as $var_string){ global $$var_string; if ( (gettype($$var_string) == 'string') || (gettype($$var_string) == 'boolean') || (gettype($$var_string) == 'integer') || (gettype($$var_string) == 'double') ) { print('&lt;strong&gt;'. $var_string . ': &lt;/strong&gt;' . $$var_string . LB); } elseif ( (gettype($$var_string) == 'array') || (gettype($$var_string) == 'object') || (gettype($$var_string) == 'resource')){ print('&lt;strong&gt;' . $var_string . ': &lt;/strong&gt;'); print_r($$var_string); print(LB); } } } vc('var1'); vc('var2'); vc(array('var1', 'var2')); </code></pre>

    1. COTip 1: Give functions and variables meaningful names to indicate what they do/represent. You'll thank yourself for it in the future :)

    3. COYou know that now, but we don't and you'll forget very quickly. Trawling through code with variable/function names that are meaningless is hard. Code you post to ask for help on should be as clear as possible with good variable/function names so you make it easier for those who may wish to help you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
