[SOLVED] I need some informatio about functions!

[samoi]

Hi guys,

 

I have a question about functions.

 

I'm wondering if I can put if() statement inside a function?

 

 

like this [BUT IT DID NOT WORK THIS WAY].

 

<?php
require_once("samoi.php"); // which has the information of the database.

$username = $_POST['username'];
$password = $_POST['password'];

function samoi()
if(!$username || !$password)
     {
      echo "Insert inputs";
      }

else
         {
          $sql_insert = "INSERT INTO sam (username, password) VALUES ('$username', '$password')";
          $qry_insert = mysql_query($sql_insert);
          echo "the data has been saved!";
         }

function samoi();
?>

 

 

any ideas?

functions require opening and closing brackets

 

function blah () {

...

}

yes you missed the essential curly brackets Crayon Violent has said and yes you can nest as many if..else statements as you like inside and outside of functions and classes.

you must pass values to your function like this

<?php
require_once("samoi.php"); // which has the information of the database.

$username = $_POST['username'];
$password = $_POST['password'];

function samoi($username, $password){ // add start function block and function variables
if(!$username || !$password)
     {
      echo "Insert inputs";
      }

else
         {
          $sql_insert = "INSERT INTO sam (username, password) VALUES ('$username', '$password')";
          $qry_insert = mysql_query($sql_insert);
          echo "the data has been saved!";
         }
} // end function block
samoi($username, $password); //call function with values
?>

What is the advantage to creating a function?

[.josh]

if you only plan on calling it once, then there's no advantage whatsoever.  The point in putting something in a function is if you have a chunk of code being used over and over, you can just put a label on it and call the label.

Thank you all guys

 

you helped me really

 

there's no advantage, but I just want to make sure that a function can include if statements

 

that's it.

 

 

I have question for you all,

 

I'm a beginner to the PHP, and I need your advice in how to learn it and be good at it!?

 

I love it so much, but sometimes I get angry and sad that I cannot handle a simple script

 

Don't suggest me to visit PHPmanual I'm sick of it!

 

Thank you in advance!

Sorry to hear that you're sick of the manual...it should receive some kind of award for best manual ever written (it probably has, multiple times).
