Can someone show me how to properly write this short if statement?

[KDM]

if ("$car_class") == FALSE {
		echo   '<span class="warning">*</span>';
	}

 

 

Here is my error thanks

Parse error: syntax error, unexpected T_IS_EQUAL in /home/content/30/6371630/html/register.php on line 421

Read the manual - http://se2.php.net/manual/en/control-structures.if.php

[premiso]

Since maq is my lover and everything I've ever wanted, just lazy:

 

if ($car_class == FALSE) { 
    //echo here
}

[AbraCadaver]

Will evaluate if $car_class evaluates to any value that is considered false:

if ($car_class == FALSE) {
   echo   '<span class="warning">*</span>';
}

This will do the same:

if (!$car_class) {
   echo   '<span class="warning">*</span>';
}

This will check to make sure the value is actually boolean false:

if ($car_class === FALSE) {
   echo   '<span class="warning">*</span>';
}

 

 

[IrOnMaSk]

is that line 421?

if ("$car_class") == FALSE {
		echo   '<span class="warning">*</span>';
	}

here's the structure of if statement

   if(  condition   )
   {
      //execute code if condition is true
   }

you didn't close the codition ")"

so close the condition after the ==False

in this case if the OP doesnt even understand how to write a simple if statement, i beleive that the manual is the best place for him/her to look and understand PHP..i agree with what Maq posted, will lead to more enlightment here

i usually have a hard time understanding the manual actually because they don't explain much just show you with examples...

i go there for syntax not for understanding but not all people are a like we all are unique and special like everyone else lol

[Maq]

we all are unique and special like everyone else lol

Some of us more than others. *cough* premiso *cough*

 

KDM, did you figure it out?

it is a mixture of text explanation and written examples.. it is absolutely essential to look there to fully understand many PHP concepts..

that made me laugh..

totally agree. i feel like the manual is for the elites lol, maybe just me

and there's a fine line between being uniqu/speical and nerd/geek

Oops the second quote should be this lol

thanks, very well said.

Thanks for the help. I was trying to make it so that if the send button is pressed and $car_class is FALSE it would display the warning.

[IrOnMaSk]

if you want to check if the send button was click

use

  if(isset($_POST['subment']))
  {
     if( condition)
     {
        //if $car_class is false execute code here
      }
  }

the isset will check if the button is pressed assument the button is named 'submit'

if you want to check if the send button was click

use

  if(isset($_POST['subment']))
  {
     if( condition)
     {
        //if $car_class is false execute code here
      }
  }

the isset will check if the button is pressed assument the button is named 'submit'

 

in this case if it is named.. "subment" ...

  if(isset($_POST['subment']))
  {

     {
        //if $car_class is false execute code here

  }

yup, thnx AK47

i can't type today :'(

if you want to check if the send button was click

use

  if(isset($_POST['subment']))
  {
     if( condition)
     {
        //if $car_class is false execute code here
      }
  }

the isset will check if the button is pressed assument the button is named 'submit'

 

@KDM: FYI- this could be condensed into one statement if you wanted; like:

if (isset($_POST['submit']) && $car_class == FALSE) {
// code to execute
}

Thanks for the help! I tried if isset before but didn't use the post variable. And I had to change submit to send. It's working fine now. Thanks a lot. I learned something.
