  • PHP Global variable in class is reset

    - by Robert
    I have a web form that manipulates records in a MySQL database. I have a method for displaying an edit interface for both creating new records and editing them if ($_POST['new_page']) { print "<h2>Create new page</h2>\n"; $isNew=1; $this->EditForm(); } else if($_POST['edit']){ print "<h2>Edit page</h2>\n"; $isNew=0; $this->EditForm(); } I am trying to use the global variable $isNew to determine where a record is to be added or updated. However, whenever my SaveChanges() function is run, $isNew is always 0. $isNew is declared immediately after the class declaration, outside all of the functions. class Editor{ public $isNew;

    I am looking for a simple formula to do the calculation on two fields that are variable, for e.g., c1 has 100 and c3 has 150 and I want to calculate an increase/decrease percentage, but the trick is the cell values change every month.

  • Variable scoping and the jQuery.getJSON() method

    - by jerome
    The jQuery.getJSON() method seems to ignore the normal rules of scoping within JavaScript. Given code such as this... someObject = { someMethod: function(){ var foo; $.getJSON('http://www.somewhere.com/some_resource', function(data){ foo = data.bar; }); alert(foo); // undefined } } someObject.someMethod(); Is there a best practice for accessing the value of the variable outside of the getJSON scope?

  • anonymous function variable scope [js, ajax]

    - by arthurprs
    $(".delete").click( function() { var thesender = this; $(thesender).text("Del..."); $.getJSON("ajax.php", {}, function(data) { if (data["result"]) $(thesender).remove(); // variable defined outside else alert('Error!'); } ); return false; } ); This can cause problems if user clicks on another ".delete" before the ajax callback is called?

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?
