More form bother

ianco · September 29, 2009

HI all, I have a form with checkboxes and text boxes. When the check box is ticked some text appears which contains the variable text box. However I want to post html in the text box so it displays in the php output but unless i change everything first to eg. < then it doesnt appear. What i want is for the php to automatically change "<" to "<" etc. i've seen the htmlentities() but dont know where to put it. Any ideas?

Here's the code

<?PHP
$ch1 = ' ';
$ch2 = ' ';
$ch3 = ' ';

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

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

$ch1 = $_POST['ch1'];

if ($ch1 = 'net')
{

$ch1 = '<UL><br>
<LI><br>
<a href="' . $_POST['num'] . '.pdf">' . $_POST['det'] . '</a><br>
</LI><br>
<UL><br>
<LI>(PDF format, <!-- #config SIZEFMT = "ABBREV" --><!--#fsize file="' . $_POST['num'] . '.pdf"--> KB)</LI><br>
</UL><br>
</UL><br>
<br>';

}
} etc.
?>


<?PHP print $ch1; ?>

---------------------
<Input type = 'Checkbox' Name ='ch1' value ="net" 
<?PHP print $ch1; ?>
PDF<br>
Details: <br>
<input type="text" name="det" /><br>

I'm not 100% sure what you are asking, but perhaps this is what you need? :

$my_string = <<<EOT

<p>This is my return code $with_a_variable from {$_POST['var']}</p>

EOT;

$my_string = htmlentities($my_string, ENT_QUOTES);

ENT_QUOTES causes both single and double quotes to be converted as well, I almost always use that.

So i should put $my_string = <<<EOT under $ch3 = ' '; and EOT before the last ?> ?

What about $my_string = htmlentities($my_string, ENT_QUOTES);?

jon23d · September 29, 2009

<<<EOT && EOT; is heredoc sytax, its good for when your string is very complex. If its really messy, then consider using output buffering and require_once.

Go read about htmlentities though, its super easy, it converts the characters that your browser views as html, to something that isn't parsed.

Ive tried

' . echo htmlentities($_POST['detcif'], ENT_QUOTES) . '

but i get

Parse error: syntax error, unexpected T_ECHO in /www/uuuq.com/i/a/n/iancoates/htdocs/development/checkBoxes.php on line 59

i guess it's not in the write place

Here is my php file

<?PHP

$ch1 = ' ';

$ch2 = ' ';

$ch3 = ' ';

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

/* pdf */

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

$ch1 = $_POST['ch1'];

if ($ch1 = 'net')

{

$ch1 = '<UL>

<LI>

</LI>

<UL>

<LI>(PDF format,  KB)</LI>

</UL>

';

}

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

$ch2 = $_POST['ch2'];

if ($ch2 = 'word') {

$ch2 = '<UL>

<LI>

<a href="' . $_POST['num'] . '.txt">' . $_POST['dettxt'] . '</a>

</LI>

<UL>

<LI>(CIF format,  KB)</LI>

</UL>

';

}

/* cif */

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

$ch3 = $_POST['ch3'];

if ($ch3 = 'excel') {

$ch3 = '

<UL>

<LI>

<a href="' . $_POST['num'] . '.cif">' . $_POST['detcif'] . '</a>

</LI>

<UL>

<LI>(CIF format for CIF viewers,  KB)</LI>

Try something like this:

Oh, and watch out for lines like:

if ($ch2 = 'word') { <-- assignment in condition, it this what you really mean? This will ALWAYS evaluate to true. == is for comparing, = is for assigning, === is a strict comparison of obj type

That kinda works but it removes my formatting tags and changes some " marks. Can it just act on the $_POST['det'] bit?

jon23d · September 30, 2009

echo htmlentities(str_replace("__my_stuff__", $contents, $page_template));

to:

echo nl2br(htmlentities(str_replace("__my_stuff__", $contents, $page_template)));

Will convert the line breaks to after changing the rest to entities, thus preserving your breaks.
