Delete text between and including identifying strings

Submitted by Benjamin Melançon on August 25, 2007 - 6:31pm

Internet answered this question for Agaric, and we'll make it easier for the next person to find the answer!

remove HTML within markers
regexp strip all between two snippets
regexp delete between two keywords
php delete between strings

There's a great, informative post – just in response to a question on a forum – on how to do it with a regular expression here:

With this answer:

$string = preg_replace( '/\<body\>.*\<table/Usi', '<body><table', $string );

Our modification (main difference, not re-adding the search strings) worked quite nicely to remove unwanted text hardcoded into another Drupal module, the otherwise wonderful Video module in 4.7:

Scale a square's dimensions with PHP

Submitted by Benjamin Melançon on August 25, 2007 - 6:07pm

Or determine and apply any ratio.

Agaric needed this for a Drupal module, but this is general PHP that should work for anything.

php scaling function length height
calculate a ratio

Below, Agaric's function for scaling two dimensions maintaining their aspect ratio given a limit for one or both dimensions (or a percentage, but in retrospect it is very silly to wrap multiplication in a function).

Freelance or Small Business, what about Cooperative?

Submitted by Benjamin Melançon on August 25, 2007 - 10:19am

The Web Design Business Kit, by Brendon Sinclair, provides good advice, at least in the free sample chapters.

It does however, set up an absolute two-choice approach: freelancing, or owning a small business.

Not a token nod to a collective, co-operative form of organization? Equality, liberty, fraternity? And this from an Sinclair, who appears to take the view that work-or-starve is its own sort of slave labor in the introduction summary:

Find the next largest key in an array

Submitted by Benjamin Melançon on August 25, 2007 - 7:58am

php find the next largest key in an array
php find the next greatest key in an array

There is undoubtedly a better way, but recursion has melted my brain and search engines aren't saving me.

So this is what I did... actually, I used another approach entirely that didn't need this. But array_keys is how I would have started, then sorted it, and then had a foreach that compared my key to the keys it got as it walked through, and broken out of there with the new key the first one that was larger.

php find the next largest key in an array
php find the next greatest key in an array

There is undoubtedly a better way, but recursion has melted my brain and search engines aren't saving me.

$terms_on_this_level = array_keys($parents);

I know there would have been a better way, but it's moot to me know anyway... until I search for this answer again and find my own, deeply unfulfilling, page.

Freelinking not working? Check WikiTools settings.

Submitted by Benjamin Melançon on August 23, 2007 - 1:40pm

There's a setting in wikitools that literally says hijack freelinking . It has to be unchecked.

Dan figured this out.

Agaric Design... figuring stuff out little by little.

Delete from Drupal variable table where name LIKE

Submitted by Benjamin Melançon on August 23, 2007 - 10:17am

delete from variable where LIKE drupal

There are occasions when the usual approach:
variable_del('cmt_example_variable');
won't work.

This is not recommended as a shortcut, and in fact even here is problematic should there ever be a module called cmt_teaser_

/** * Implementation of hook_uninstall(). */ function cmt_uninstall() { db_query("DELETE FROM {variable} WHERE name LIKE 'cmt_teaser_%'"); cache_clear_all('variables', 'cache'); }

So this is bad practice, but I don't see

I'm not going to keep track of all the node types that ever were available to Community-Managed Taxonomy and might have had this variable created. I suppose I could just delete the variables for node types currently available to CMT and possibly leave a few variables, is better than the even slighter risk of deleting another modules variables?

Unadorned FALSE or TRUE not working in FAPI?

Submitted by Benjamin Melançon on August 23, 2007 - 8:28am

This is a Drupal 5 question. Why doesn't this work?

$form_add['cmt_teaser'] = array( '#type' => 'radios', '#title' => 'Community-managed taxonomy display', '#options' => array( TRUE => t('Show term managing form on teasers and full content.'), FALSE => t('Show term managing form on full content'), ), '#default_value' => variable_get('cmt_teaser_' . $type . '_teaser', FALSE), '#description' => t('CMT forms can become large and complex, so displaying them on the teaser is usually not recommended.'), );

But this does:

Display everything about a form in Drupal 5

Submitted by Benjamin Melançon on August 23, 2007 - 6:18am

To display everything about every form, Agaric uses this in a form_alter hook implementation:

drupal_set_message('<p>Form ID: ' . $form_id . '</p><pre>' . print_r($form, TRUE) . '</pre>');

In fact, we wrap it in our own function, which we have in our development module, agaric:

This is a more... complete... overwhelming... version of the line Agaric suggested for displaying the form ID of all forms.
