how to call a method from hreff?
April 15, 2013 10:30PM
Ok, first off I am not doing this course,
but after reading a post from another student asking about classes in 2613... well my ego got the best of me and I decided to rewrite my web page in a more OOP way.

(and I know its not needed in year 2, but I like learning this and am impatient, so please help me)

My Question:
so I have a person class...
with methods...

a constructor method and a display method that does something like this...

Language: PHP
echo "<td>"".$this->Username . "</td><td><a href=PHP/deleteP.php?player_id=".$this->ID.">Delete</a></td></tr>";

but I have a method to delete this person from the db...

Language: PHP

but as this is sitting server side... how do I call this method in the hreff... is it possible, can I do it with a button?
should I even have a method like this?
or just use my previous code: (that works?)

Language: PHP

You do not call the method in the a href - you merely send the id to the delete page with th a href. There the id is caught and used in the method. It appears a bit of an overkill - I'll just have a simple delete statement since the query is specific i.e. to delete a player. Why write a 4 line function when a one line delete query can do the same job? Not to say you must not.... but OO is not always better. A delete method that can be used with more than one table is useful.

Thanks Mac, appreciate the help
Header or include... can switch statement be rerun?

sorry for stupid question previously...
might have another though...
I have a action page...
and depending on the action it will include diffrent things...

Language: PHP
switch($_REQUEST[';Action';]){ case "ViewAll" : //some code here $page = "otherPage"; case "Delete": $Fixtures[0]=new Fixture(';';,';';,';';,';';); $Fixtures[0]->ID=$ID; $Fixtures[0]->Delete(); //what to do here... I need to refresh the entire page or table.. so would like to jump to the above code "Viewall" action... header ("Location: ?Controller=Fixtures&Action=ViewAll"); //this does not work (guessing its because of me including this into another page??   break;}   include( ';Views/'; . $page . ';.php';);

can someone help?

Either headers already sent, or remove space between location: and ?, but add full page URL

Else try:

Language: PHP
echo "<meta http-equiv=';refresh'; content=';0;url=http://........';>";
