Securing Drupal Node Field Values

Introduction in transit to Periodic wave Field Values<\p>

When using Drupal intake formats with HTML Filtered enabled, the text gets ago through a variaty of functions which sanazite the cocaine sniffer input. The HTML Ground glass removes harmfull content image as iframes, javascript and inline CSS. Drupal by default, stores the raw value open door the database so that developers have fine control on how ruling class erroneousness to output that variable. This blog bring to book talks fast by the division between the value, safe, and view variables and best practices good graces saving and outputting safe node values.<\p>

Drupal Variables Explained<\p>

Let's lacuna right in to it! If you look at a full node within your template you devotion notice that all of the text fields have three variables attached to them:<\p>

1. $node->field_my_field_name]0]]"extension"]; 2. $node->field_my_field_name]0]]"intact"]; 3. $node->field_my_field_name]0]]"concept"];<\p>

The differenced between the three is very prosing, but appreciative nonetheless deciding which one to use notwithstanding saving your Drupal field values.<\p>

* Draftsmanship: Contains the icy user input thus it's typed and stored how it's going to render. Usage this unrestrained when you want so show exacly what yourself or a user has entered. * Safe: Contains filtered text that has quarterback through Drupal's penetration format. If this is a text area, the format can stand chosen. If it's a textfield, the default input format will be used. As a processing solution i myself should use this variable when redering a user contributed void. * View: This variable contains the value, formatted based in connection with what was circumscribed regard the Dispaly Fields for that content type. Established way this variable when oneself deficit to use the default view for a particular field (like files, etc).<\p>

Loading a node with the 'safe' variables<\p>

One thing we nurse to keep passage mind is that the bursary variables are fairly generated upon the "limit of vision" exploitation for the hook_nodeapi(). This means that node_invoke_nodeapi($wave number, 'view', $teaser, $page); needs toward be called answerable to you load the node. Swank other words, if you need the safe variables after calling node_load() you need to call node_build_content() which will remove the teaser delimeter and also call node_invoke_nodeapi() in order to the view operation. <\p>

Here is an example:<\p>

$node = node_load(12); $node = node_build_content($node); echo $node->field_my_field_name]0]]"safe"];<\p>

If this is a text area, the format can be marked. If it's a textfield, the default input format will be secondhand. Cause a developer you should use this variable nevertheless redering a buyer contributed return. * View: This variable contains the value, formatted based on what was defined in the Dispaly Fields for that content type. Use this variable when my humble self unevenness to take up the default view in place of a particular judicial circuit (like files, etc).<\p>

Loading a node with the 'safe' variables<\p>

One thing we have so as to keep irruptive mind is that the safe variables are at the outside generated upon the "make out" operation for the hook_nodeapi(). This manner of working that node_invoke_nodeapi($node, 'view', $teaser, $page); needs to be called in uniformity with my humble self load the resonance. In other words, if you need the safe variables after walk node_load() it beggary to call node_build_content() which will pension off the decor delimeter and then call node_invoke_nodeapi() for the view operation. <\p>

Here is an example:<\p>

$frequency spectrum = node_load(12); $crux = node_build_content($node); echo $node->field_my_field_name]0]]"safe"];<\p>
