php within php

[ianco]

I want to display text when a tick box is ticked. This I can do BUT the text i want to display has a number of php tags(<?php echo $_POST["det"]; ?>). These wont display. Is it possible? Does the 'Some text' need to be withing brackets?

 

The php is...

 

if (isset($_POST['Submit1'])) {

 

if (isset($_POST['ch1'])) {

$ch1 = $_POST['ch1'];

 

if ($ch1 = 'net') {

$ch1 = 'Some text containing php tags';

}

}

}

 

Thanks

Use htmlentities() with the 2nd parameter set to ENT_QUOTES

 

The < and > of the php tags look like html tag delimiters and cause the php code to be treated as a html tag.

Hmm...

 

Sorry i'm a beginner at this. I want the php to output text.

 

Where do i need to insert the htmlentities()?

 

 

Thanks

couldn't u just seperate it

echo "<"."?"."php "."bla bla bla text "."?".">";

assuming $ch1 is the text you want to output

echo htmlentities($ch1);

@dad00 -

The < and > of the php tags look like html tag delimiters and cause the php code to be treated as a html tag.

If you literally output < and > using any method, the browser will treat them as the start and end of a html tag. You must convert them to html entities to so that they are not operated on by the bowser.

I want the browser to read the php within the <> tags within the other php code though. if i change to < then it will appear as <

[mikesta707]

if you want the PHP to be parsed, then just echo it. But if you are parsing it anyways, why not just write the lines? there is also the eval function.

$php = "<? echo \"My name is John\"; ?>";
eval($php);
//output:
//My name is John

Cant get tis to work, where do i put the eval code? tried in a few places with no luck, just causes parsing errors?

 

Sorry for being a pain

Browser's don't read php code because php is a server side scripting language.

 

Perhaps if you explained exactly what you are trying to accomplish with a real example of the code you want to use.

No. It won't. At least try something first.

<?PHP

$ch1 = 'unchecked';

$ch2 = 'unchecked';

$ch3 = 'unchecked';

$ch4 = 'unchecked';

$ch5 = 'unchecked';

 

 

 

if (isset($_POST['Submit1'])) {

 

 

 

if (isset($_POST['ch1'])) {

$ch1 = $_POST['ch1'];

 

 

 

if ($ch1 = 'net') {

 

$ch1 = '{<UL><br>

<LI><br>

<a href=<?php echo $_POST["num"]; ?>.pdf><?php echo $_POST["det"]; ?></a><br>

</LI><br>

<UL><br>

<LI>(PDF format, <!-- #config SIZEFMT = "ABBREV" --><!--#fsize file="<?php echo $_POST["num"]; ?>.pdf"--> KB)</LI><br>

</UL><br>

</UL><br>}';

 

}

}

 

if (isset($_POST['ch2'])) {

$ch2 = $_POST['ch2'];

 

if ($ch2 = 'word') {

$ch2 = 'checked';

}

}

 

if (isset($_POST['ch3'])) {

$ch3 = $_POST['ch3'];

 

if ($ch3 = 'excel') {

$ch3 = 'checked';

}

}

 

if (isset($_POST['ch4'])) {

$ch4 = $_POST['ch4'];

 

if ($ch4 = 'web') {

$ch4 = 'checked';

}

}

 

if (isset($_POST['ch5'])) {

$ch5 = $_POST['ch5'];

 

if ($ch5 = 'php') {

$ch5 = 'checked';

}

}

}

 

?>

 

<?PHP print $ch1; ?><br>

<?PHP print $ch2; ?><br>

<?PHP print $ch3; ?><br>

<?PHP print $ch4; ?><br>
