Re: Vista vs Microsoft Visual C++ 6.0

Given that Visual C++ 6 is 10 years old I would bet the farm that it's compatibility. I would highly suggest you upgrade to a version newer than a decade old.

Re: public/private in php

The same holds true for PHP for both variables and functions.

class SomeClass{
  private $test1;
  public $test2;
  private getTest1(){return $this->test1;}
  public getTest2(){return $this->test2;}
}

Then if you try to access them

$blah = new SomeClass();
$test1 = $blah->getTest1(); //error
$test2 = $blah->getTest2(); //works

Re: HTML title image

That is called a favicon, it's pretty easy to implement just toss this in your <head></head> section.

<link rel="shortcut icon" href="location of your image here" type="image/type here" />

So if I had an image called myFavicon.jpg I would use.

<link rel="shortcut icon" href="myFavicon.jpg" type="image/jpeg" />

Re: New to Ajax

You don't need a database to use Ajax. Ajax's purpose is to allow you to send asynchronous requests to a separate page and handle that request (hence the name). You can, if you want, make a request to a page which interacts with the database but Ajax itself shouldn't really interact with the database for security reasons.

Re: Hyperlink in email doesn't work...why?

OK, there is another post that deals with almost the exact same topic. You can't use relative links in emails. The recipient's email client doesn't know what or where resetPassword.php is, nor does it know where 'images/emailNotGone.png' is. You have to use absolute links, ie., http://www.example.com/resetPassword.php

Re: decimal (10,2) limit

You would test the form field with a regex like this.
(10, 2) in database means 10 numbers, 2 decimal places. so 12345678.90 is valid.

var testRegEx = /[0-9]{1,8}\.?[0-9]{0,2}/
var isValidNumber = form.formField.value.match(testRegEx);

Re: perl rather than php because no good php books. comment please.

Firstly I would have to significantly disagree with the lack of good PHP books. The reason there are "good" books for Perl/Python is because the users of those languages are fanboys/fangirls and would hate to decry their precious language. PHP is so widely spread at this point it is absurd to think that there are no good books on it. Any of the O'Reilly books are a good read, not to mention the entire PHP.net website which is pretty much unrivaled in language documentation in one source(aside from Java). Not to be mean but you could, you know, try reading one yourself instead of letting out a very loud sheep noise at someone else's review.

Re: Drop down list with images.

Well it can't be done with a normal select box, you have to pretty much hack a bunch of divs and/or spans together to act like a select box. It's been done with a few AJAX autocomplete scripts that you can tear apart.

Re: delete statement php/sql

In syntax "markup" anything in angle brackets, < >, is a required field, anything inside brackets [ ], is optional. So DELETE FROM <table> means that you must have something where it says <table>, ie., DELETE FROM someTable .

That said the query format is

DELETE FROM <table > [, table [...]] [WHERE <col> = <value> [LIMIT <offset>[,<number>]

Meaning that you can do DELETE FROM someTable, someSecondTable WHERE row = 3 LIMIT 0,2 Which would delete everything from someTable and someSecondTable where row is equal to 3. Or I could simply do, DELETE FROM someTable WHERE row = 3

Re: errors since upgrade to php 5.2

Re: errors since upgrade to php 5.2

It works because it's not an error since PHP is capable of implicit initialization meaning a variable is declared as soon as you use it if it was not declared before as opposed to C or C++ which requires explicit initialization.
Aside from that I meant the actual code for the function, the description of it doesn't really help when debugging it :)

Re: errors since upgrade to php 5.2

Well both errors are pretty helpful since they explain in plain English exactly what is going wrong.
The first

Notice: Undefined index: submit in /var/www/vhosts/domain/httpdocs/Directory/form.php on line 270

Tells you that there is an Undefined index. In this line

if ($_POST['submit'] == "Submit Search") {

The 'submit' is called an index as it is an index to the location in the array. So what the notice is saying that there is nothing defined in the 'submit' position in the $_POST array.

For the second could you show the definition of your trim_array function because it isn't a built in PHP function unless it's new to 5.2

Re: errors since upgrade to php 5.2

Make sure you go over to http://www.php.net/releases/ and check the changelogs for compatibility and major upgrades that can break code. Checking changelogs is always good practice when making an upgrade to prevent things like this.

Taming the serif: Darn you Web 2.0

Is it just me or have serif fonts become the new go-to font of Web 2.0 sites. Out the window with you old, boring sans-serif Verdana. Who needs you Arial? We have Georgia, glorious Georgia, or even *gasp* Garamond. Has the serif laid it's pointy edge into the blunt broadside of the sans-serif fonts(yeah, that's a little over the top, wanna fight about it?) or do you believe that each has it's place... like when a 9 shouldn't look like it's about to crash through the floor of the current line.

Re: Creating a Cookie with a Counter

if (isset($_COOKIE['$Username']))
    $visits = $_COOKIE['$Username'];

Never works because variables in single quotes ', aren't parsed. You need double quotes, ie.,

if (isset($_COOKIE["$Username"]))
    $visits = $_COOKIE["$Username"];

You have to do that for all of those variables in there.

Re: Parse error: syntax error, unexpected $end

Any particular reason why you are escaping these variables in this section?

print "<BR><BR>";
\$row2=mysql_fetch_array(\$content2);

print "<BR><BR>";
\$row3=mysql_fetch_array(\$content3);
\$display_content3 = \$row3['content3'];
print \$display_content3;
print "<BR><BR>";

Aside from that, the unexpected $end error comes from a missing or extra } somewhere.

Re: JavaScript form validation - please help

Good looking out ~s.o.s~, maybe something along the lines of this.

/**

 * 
 * @param elements   Array of required field IDs
 * @param parentForm ID of the form
 * @param setvalTar  ID of a hidden field to be set(optional)
 * @param setval       Value for setvalTar
 */
function verifyForm(elements,parentForm,setvalTar,setVal)
{
    var valid = true;
    for(i=0;i<(elements.length);i++){
        if($(elements[i]))
        {
            $(elements[i]).value = $(elements[i]).value.replace(/^\s(.*)/,'$1');
             $(elements[i]).className = ($(elements[i]).value == "")?'txtError':null;
            valid = ($(elements[i]).value == "")?false:valid;
        }
        else valid = false;
    }
    $('error').style.display = (valid)?'none':'';
    $('error').innerHTML = (valid)?'':'<b>Please fill in the required fields</b>';
    if(setvalTar != null && setVal != null)
        setValue(setvalTar,setVal);
    if(parentForm != null && valid)
         $(parentForm).submit();
    else return valid;
}

Aside from that, I also forgot to mention that you must have a CSS class that is applied to the textbox if there is an error, in this case it is called txtError but you can name it whatever you like and just change the code.

Re: JavaScript form validation - please help

This is a little function I wrote to verify form fields, all you need is an div with the id "error" to take the output.

/**
 * Make sure required fields are set on a form
 * 
 * @param elements   Array of required field IDs
 * @param parentForm ID of the form
 * @param setvalTar  ID of a hidden field to be set(optional)
 * @param setval  	 Value for setvalTar
 */
function verifyForm(elements,parentForm,setvalTar,setVal)
{
	var valid = true;
	for(i=0;i<(elements.length);i++){
		$(elements[i]).className = ($(elements[i]).value == "")?'txtError':null;
		valid = ($(elements[i]).value == "")?false:valid;
	}
	$('error').style.display = (valid)?'none':'';
	$('error').innerHTML = (valid)?'':'<b>Please fill in the required fields</b>';
	if(setvalTar != null && setVal != null)
		setValue(setvalTar,setVal);
	if(parentForm != null && valid)
		 $(parentForm).submit();
	else return valid;
}

Then in an html form you would have something like

<div id='error'></div>
<form action="blah.php" method="post">
    <input type="text"  name="fname" id="fname" />
    <input type="text" name="lname" id="lname" />
    <input type="button" onclick="if(verifyForm(['fname','lname'])){window.location='test.php';}" />
</form>

Re: Need help in javascript and modal window

Well the only thing you need for a modal window is two divs, and outer div to make the page modal and an inner div to hold the modal content. For example

<html>
<head>
<title>Blah</title>
<style type='text/css'>
   .modal
   {
      z-index:998;
      height:100%;width:100%;
      position:absolute;
      left:0px;top:0px; 
   }
   .modalContent{  z-index:999; }
</style>
</head>
<body>
   <div id='hello'>
       <a href='#'>You can't click on me!</a>
   
        <div id='modal' class='modal'>
            <div id='modalContent' class='modalContent'>
               <a href='#'>You can click on me though!</a>
            </div> <!-- end modal content div -->
        </div> <!-- end modal div -->
    </div><!-- end hello div -->
</body>
</html>

With that said, if you know how to do all those effects in a modeless div then you know how to do them in a modal div. Just place the content inside the inner modal div (modalContent)

Re: Help learning dynamic development

Well it really depends on how you want to build, I don't really have a lot of experience in CF and don't really care to but one of the main things that drew me to PHP was just how much information there is out there for it, mainly due to it being open source. But don't think PHP and CF are your only choices; Python is making it's way into the web with things like Django, and then there is Ruby on Rails which I won't comment on due to lack of experience.
