Wild char IF

vipernet · 20-May-2008, 09:45 AM #1

Never really done this before so kind of new with it all. I tried to find an answer at php.net, no luck.

Here is the script that handles what I want to echo:

PHP Code:

  $count = 1 + $s ;

 
//Table within Loop

echo "<table border=\"1\" align=\"center\">";

echo "<tr><th>Item</th>";

echo "<th>System Name</th>";

echo "<th>Room</th>";

echo "<th>Brand</th>";

echo "<th>School</th>";

echo "<th>Sticker</th></tr>";

 
// now you can display the results returned

  while ($row= mysql_fetch_array($result)) {

  $title = $row["item"];

  $title2 = $row["computer_name"];

  $title3 = $row["room"];

  $title4 = $row["brand"];

  $title5 = $row["school"];

  $title6 = $row["sticker"];

echo "<tr><td>";

echo "&nbsp;$title";

echo "</td><td>";

//echo "&nbsp;$title2";

if ($title== "printer")

  {

echo '<a href=" http://'.$title2.'" target="_blank">'.$title2.'</a>';

}

else

{

echo '<a href=" http://'.$title2.':5800" target="_blank">'.$title2.'</a>';

}

What i want is to be able to make the expression a wild char

PHP Code:

  if ($title== "printer")

and echo the true/false statement

er that doens't make any sense. If you make it a wildcard, then the if will always kick in.

but if you mean you want to use regulare expressions to match things then try this:

I'm not to hot on regex but will give it a go.

Say you have a string like this "test-printer-on-computer_a" and you want to match the word printer then you could try:

PHP Code:

   
if (preg_match('/printer/i', $title)) 

  { 

echo '<a href=" http://'.$title2.'" target="_blank">'.$title2.'</a>'; 

} 

else 

{ 

echo '<a href=" http://'.$title2.':5800" target="_blank">'.$title2.'</a>'; 

}

awesome dude, worked like a champ.

Sorry I wasn't descriptive in my last post.

Within the SQL database the text within the fields are (printer, color printer, desktop, laptop...etc) so i wanted to filter them using a common word = printer.

well if your gonna do that then why use the regex engine? Its far slower than the native php functions like, say, strpos

$string = "I am the most awesome person ever";
if(strpos($string,"awesome")) echo "im so awesome";

this if will fire because the strpos function found the word 'awesome' in the phrase. Just remember though, that strpos has the arguements 'haystack' THEN 'needle', as opposed to most string functions.

thank you. using regex for simple matching is a pet peeve of mine.
but then again, so is echoing a bunch of consecutive lines of html
?>
<your>
<html>
<here>
<? // is much more readable AND easier on the parser

Another option would be

echo "<table border=\"1\" align=\"center\">
<tr><th>Item</th>
<th>System Name</th>
<th>Room</th
<th>Brand</th>
<th>School</th>
<th>Sticker</th></tr>";

Easier to read, somewhat easier on the parser(not as much as ending the tags though), and it gives you line breaks in 'view source'.

Also, the code i put up was wrong, the if statement would preferably be
if(strpos($string,"phrase") !== false){do action}
