Don't use one big echo, break it up:

<?php

echo "
<table width='528px'>
<tr>
<td>
</td>
<td>
<center><font size='5'>$tittle</font></center><br>
</td>
</tr>
<tr>
<td>
</td>
<td>
$message
</td>
</tr>
<tr>
<td>
</td>
<td>
<font size='1'>Posted By:<font color='green'>$author</font> on <font color='gray'>$date</font> at <font color='gray'>$time</font></font>
<input id='delete' name='delete' type='submit' value='Delete' >";
if ($_POST['delete']) {  echo "DELETED";     }
echo "<td>
</td>
</tr><br><br>
</table>

";
?>

Thanks for the quick replies :D

 

 

@Ken i tried breaking the echo´s up like you just did, but it still is not working :S

 

@Rifts , i think the line of code giving a problem here its

if ($_POST['delete']) {  echo "DELETED";     } 

that is why  i am asking if its possible to write an if inside an echo :)

 

 

EDIT:

 

 

i just tho  its not working because this line is inside the echo

(1)

<input id='delete' name='delete' type='submit' value='Delete' >

 

and this like its outside the echo

(2)

if ($_POST['delete']) {  echo "DELETED";     } 

 

 

and since they are related(line 2 asks line 1) maybe thats why they dont work? (just an idea) XD

What's not working? What's it supposed to do? We may need to see more of your code.

 

Ken

 

Ill explain again :D

 

 

 

 

Okey i echoed out a table  and at the end of the table i echoed a delete button

and when i click on that delete button, its supposed to echo "DELETED"

 

this is how i have the code at the moment with modifications made

 

echo "

<table width='528px'>
<tr>
<td>
</td>
<td>
<center><font size='5'>$tittle</font></center><br>
</td>
</tr>
<tr>
<td>
</td>
<td>
$message
</td>
</tr>
<tr>
<td>
</td>
<td>
<font size='1'>Posted By:<font color='green'>$author</font> on <font color='gray'>$date</font> at <font color='gray'>$time</font></font>
<input id='delete' name='delete' type='submit' value='Delete' > ";

if(isset($_POST['delete'])) {echo("DELETED";} 

echo "
<td>
</td>
</tr><br><br>
</table>

";

within echo or string concatenation use the trenary operator instead.

 

which works like a if...else statement

 

so

echo "You have {$amt} item";
if($amt>1)
   echo 's';

 

can be written with a trenary operator as

echo "You have {$amt} item". ($amt>1?'s':'');

 

if lookes like this: {expression} ? {true result} : {false result}
