calculated field in content
23 July 2010 at 8:57pm
Hi
I'd like the person editing the page content in TinyMce to be able to insert a calculated field, eg the next 4th Friday. I have a php function that calculates the next nth specified day, but the user needs to be able to specify the week and the day. ie something like 'The next meeting is on nextdate(4,6)'.
Is this possible to do? preferably easily!
Thanks

/**
* replace string in Content
* [ Untested ]
*/
public function Content() {
$this->Content = str_replace( "nextdate(4,6)", $this->nextdate(4,6), $this->Content );
return $this->Content;
}/**
* parse next date
* [ Untested ]
*/
public function nextdate($var1,$var2) {
return "whenever";

Thanks. The numbers 4 and 6 in nextdate(4,6) are parameters and may be any numbers (the 6 could go up to 12). I don't know how to pick these out.

/**

*/
public function Content() {
//$this->Content = "The next meeting is on nextdate(4,6)";
$this->Content = preg_replace(
"#nextdate\((.+?),(.+?)\)#is",
$this->nextdate("\\1","\\2"),
$this->Content);
return $this->Content;
}/**

public function nextdate($var1,$var2) {
return "whenever";

Thanks for your help. I've decided that maybe it's not such a good idea to parse the content. Perhaps I'll try adding a page type with a couple of fields for the user to choose the parameters and put the call to the function in the template.

You can also replace values with TinyMCE and the template/snippets plug in.
