function within a if statement

[sanson06]

Hello every one

I just wanted to know how to call a function that is nested inside an if statement.

 

Thanks in advance

Don't - put the function in a separate place. Functions should be kept together and organized.

Not sure exactly what you mean.  Can you provide and example?

[sanson06]

i don't understand what you mean so here is my code:

 

<div style=" margin:auto; width:800px;">


<div style="float:left; width:800px; text-align:center; background:#000; color:#FFF;">
<h1>HEADER</h1>
</div>
<div style="float:left; width:200px; text-align:center; background:#333; color:#FFF; clear:right;">
<h1>Left</h1>
</div>
	I want to call funtion HERE
<div style="float:right; width:100%; text-align:center; background:#666; color:#FFF; clear:righ;">
<?php		// Beginning of password script
$password = "admin";  // Change Password to your need
?>
<?php 
// If the password is valid user gets access
if (isset($_POST["password"]) && ($_POST["password"]=="$password")) {
function funtTest1(){
$hide1 = "hi 1";
echo $hide1;
}
function funtTest(){
$hide2 = "hi 2";
echo $hide2;
}
?>
<!-- Start of hidden content -->


<br />
<span class="entry_title">title</span>


<!-- End of hidden content -->

<?php 
}
else
{

// If wrong password or no password
if (isset($_POST['password']) || $password == "") {
  print "<p align=\"center\"><font color=\"red\"><b>Incorrect Password</b><br>Please enter the correct password</font></p>";}
print "<form method=\"post\"><p align=\"center\">Please enter your password for access<br>";
  print "<input name=\"password\" type=\"password\" size=\"25\" maxlength=\"10\"><input value=\"Login\" type=\"submit\"></p></form>";
}
?>

</div>

<div style="float:left; width:100%; clear:both; text-align:center; background:#999; color:#FFF;">
<h1>FOTTER</h1>
</div>


</div>

Defining a function is different than invoking a function.  When you write:

 

function myFunc($arg1)
{
   // do something with $arg1
}

 

You're not actually running (invoking) the function at that point.  You're merely defining it.  All you're really doing is telling the script "Here's a custom function I wrote."

 

It makes sense to define functions outside of your script's execution flow in order to keep this distinction clear.  Function definitions can still be placed in the same file as your script, but they don't belong in conditionals or loops.

ok, so how would i do this?

 

What i want is that when the user inputs the correct password i want to make the left side bar disappear and extend the container div.

[KevinM1]

It's as simple as (pseudo-code):

 

if (/* entered password is NOT correct */)
{
   // display side bar
}

 

There's no else-clause because I'm assuming that the default state of the page wouldn't have the side bar.

 

Now, you'll have to figure out how to check that the user is logged in, how to pass that info from page to page, and how to display the side bar itself.
