IF value entered is nothing?
I forgot how to do this and I can't find anything in google.

I need a quick if to search if $gamertag has anything entered, if it doesn't i need it display an error message otherwise display the below.

Thanks.


PHP: Select all

<?php
    $answer = $_POST['style'];
    if($answer == "Homecourt #1"){
        echo "There is no Homecourt #1";}
    elseif($answer == "Homecourt #2"){
        echo "There is no Homecourt #2";}
    elseif($answer == "Homecourt #3"){
        echo "There is no Homecourt #3";}
    elseif($answer == "Gears Of War #1"){
        echo "There is no Gears Of War #1";}
    elseif($answer == "GTA IV #1"){
        echo "There is no GTA IV #1";}
            else {
                echo ("Error, please go back and try again");
                }
    ?>

Re: IF value entered is nothing?
if (isset($gamertag))

or

if ($gamertag)

or

if (trim($gamertag))

or if(trim($gamertag) != "")

should all return true if $gamertag is set. (I think...)

If i don't enter anything it still displays the above code, can you see what's wrong? I'm thinking maybe I'm missing an }?

Re: IF value entered is nothing?
There's an else { } too many ... at the bottom?! and a few things wrong.

Here's what I got when removing the echo's

PHP: Select all

<?php
if (isset($gamertag)) {
    $answer = $_POST['style'];
    if($answer == "Homecourt #1"){
        include("code/homecourt1.php");
        echo ("<br><br><br>");
        include("code/getform.php");
    
    } elseif ($answer == "Gears Of War #1") {
        include("code/gearsofwar1.php");
        echo ("<br><br><br>");
        include("code/getform.php");
        
    } elseif ($answer == "GTA IV #1") {
        echo "There is no GTA IV #1";
        
    }

else {
    echo ("Error, please go back and try again");
};
}
    
else { 
    
    echo "Please Enter your Gamertag";
}
    ?>
You're echo ("<br><br><br>"); shouldn't have the () wrapping the text

What's this?
};
}

That's ending;

PHP: Select all

else {
    echo ("Error, please go back and try again");
}; 
And then ending the

PHP: Select all

if (isset($gamertag)) { 
I think.

Re: IF value entered is nothing?
Ah ... like this then
PHP: Select all

<?php
if (isset($gamertag)) {
    $answer = $_POST['style'];
    if($answer == "Homecourt #1"){
        include("code/homecourt1.php");
        echo "<br><br><br>";
        include("code/getform.php");
    
    } elseif ($answer == "Gears Of War #1") {
        include("code/gearsofwar1.php");
        echo "<br><br><br>";
        include("code/getform.php");
        
    } elseif ($answer == "GTA IV #1") {
        echo "There is no GTA IV #1";
        
    } else {
        echo ("Error, please go back and try again");
    
    }
    
} else { 
    
    echo "Please Enter your Gamertag";
}
    ?>
Right ... that's makes sense

Re: IF value entered is nothing?
Looks much cleaner(Thanks) and I doubt you know but you also fixed another problem i had, it would randomly display a '1' after the image

Any idea as to why the isset is not working?

Re: IF value entered is nothing?
Has $gamertag been given a value before this script? How do they get to this point?

Re: IF value entered is nothing?
Put that in just now, it displays 'Enter a gamertag' yet you entered one and it displays it at the top. And if you don't enter one it displays the code i want it too.

I guess i just switch the contents of the IF around for it to work?

Fixed thanks.

Re: IF value entered is nothing?
Opps ... right...hehe ... yes

I guess it would something like this

PHP: Select all

<?php
if (isset($gamertag)) {
    
    echo "Please Enter your Gamertag";
    
} else { 
    $answer = $_POST['style'];
    if($answer == "Homecourt #1"){
        include("code/homecourt1.php");
        echo "<br><br><br>";
        include("code/getform.php");
    
    } elseif ($answer == "Gears Of War #1") {
        include("code/gearsofwar1.php");
        echo "<br><br><br>";
        include("code/getform.php");
        
    } elseif ($answer == "GTA IV #1") {
        echo "There is no GTA IV #1";
        
    } else {
        echo ("Error, please go back and try again");
    
    }
    
}
    ?>
