[RESOLVED] can't get this array to work

EPJS

I wanted to do something like "chapters" in a book, but my script isn't working.

<?php

$txtnum = array(
1 => '<p>This is some text 1</p>',
2 => '<p>This is some text 2</p>',
3 => '<p>This is some text 3</p>'
);

$gettxt = isset($_GET['txt']) and $_GET['txt'] == $txtnum;

echo "
<p><a href='?txt=1'><button>Test 1</button></a><br>
<a href='?txt=2'><button>Test 2</button></a><br>
<a href='?txt=3'><button>Text 3</button></a></p>\n
";


if($gettxt) {
	echo "
	<div class='textbox'>
	$txtnum
	</div>
	";
}

?>

I think you want:

$gettxt = (isset($_GET['txt']) and in_array($_GET['txt'], $txtnum));

However, I'm not really sure what exactly you're trying to do with the rest of the code, but I'm pretty sure you don't want to simply echo $textnum later on, as it will just print "array". You'll either want to echo a specific element of the array, or do a foreach() on it.

Oh well I was just trying to find an easy way to do this

if(isset($_GET['txt']) and $_GET['txt'] == 1) {
	echo "
	<div class='textbox'>
	<p>This is some text 1</p>
	</div>
	";
}
elseif(isset($_GET['txt']) and $_GET['txt'] == 2) {
	echo "
	<div class='textbox'>
	<p>This is some text 2</p>
	</div>
	";
}
elseif(isset($_GET['txt']) and $_GET['txt'] == 3) {
	echo "
	<div class='textbox'>
	<p>This is some text 3</p>
	</div>
	";
}

Because if I had say 20+ chapters, that would be 20+ if/else statements.

I'll try a foreach() and see if it helps.

<div>
<?php
$text = array(
   1 => "This is text 1",
   2 => "This is text 2",
   3 => "This is text 3"
);
$ix = (isset($_GET['txt'])) ? $_GET['txt'] : NULL;
if(array_key_exists($ix, $text)
{
   echo $text[$ix];
}
else
{
   echo "Default text here if no GET value or invalid GET value";
}
?>
</div>

I'm not 100% sure why but I'm getting a parse error, unexpected T_VARIABLE

Edit: Never mind I fixed it.

Thanks, that works 🙂
