Thread: PHP Programming question regarding if statements?

Hi Friends,

This is the code of my current PHP project:

mainpage.php :

HTML Code:

<div><h1> Survey Questionnaire</h1></div>

<form id="form1" name="form1" method="post" action="process.php">
<label>Name:
</label>
<input type="text" name="name" id="name" />
</label>

<label> 

Age:
<input type="text" name="age" id="age" />

Be prepared to answer some difficult questions!

</label>

</p>
</form>

process.php:

PHP Code:

<?php

$name = $_POST['name']; 
$age = $_POST['age'];
$emotion = $_POST['emotion'];
$reason = $_POST['reason'];
$color = $_POST['color'];
$season = $_POST['season'];
$music = $_POST['music'];
echo "<p>" . $name . ", you are " . $age . " years old." . "</p>";
echo "And you are " . $emotion;
echo "<p>" . $name . ", you are completing this survey because " . $reason . "</p>";
echo "Your favorite color is " . $color;
echo "<p>" . $name . ", your favorite season is " . $season . "</p>";
echo "You like " . $music . " music.";

?>

What would the if statement be if I wanted $color to change based upon the color? i.e if someone picked yellow as their favorite color how would I make the echoed $color text yellow?

I don't have time to test it at the moment but perhaps something like changing
echo "Your favorite color is " . $color;
to
echo '<p style="color:'.$color.'" >Your favorite color is '. $color.'</p>';

I've not tried with 'real' color names rather than hex numbers but think it works...

change this line

Code:

 echo "Your favorite color is " . $color;

to

Code:

echo "Your favorite color is <span style='color: $color;'>" . $color . "</span>";

echo "<span style=\"color:" . $color . "\">Your favorite color is " . $color . "</span>";
