php and mysql help

No, post #20 gives you a working search script.

What part is not working?

<form method="POST" action="resutls.php">

Again, you need to let ppl know what error(s) are displayed or what is supposed to occur within your code that isn't.

This tells ppl nothing of what the problem is - <form method="POST" action="resutls.php">

Code:

I give up :cry:

did you goto http://bob5731.no-ip.info/web/search.php

You need to upload the file "results.php" to bob5731.no-ip.info/web

Also your search script (search.php) has 2 forms on it.

Code:

---

<form name="form1" method="post" action="results.php">
<form method="POST" action="resutls.php">
Search Word: <input type="text" name="query">
<input type="SUBMIT" value="Search!">
</form>

You need to upload the file "results.php" to bob5731.no-ip.info/web

did it.

And?

It returns a blank page

The page isn't producing any output. My guess is that there is a fatal error killing the script. Try putting:

PHP Code:

---

error_reporting(E_ALL); 


---

At the top of your script. Then, see what output you get.

or the names you're searching for aren't in your db.

Maybe add this if no matches are found.

PHP Code:

---

// PHP Search Script
$result = mysql_query("select * from Name WHERE FirstName LIKE '%$query%' OR LastName LIKE '%$query%'", $db);

if (mysql_num_rows($result) == "0") {
echo "No results found!";
}
else
{
     while(list($FirstName, $LastName)=mysql_fetch_array($result)){
           echo "Result: $FirstName, $LastName <br />";
           }
}

}
lse {

// PHP Search Script
$result = mysql_query("select * from Name WHERE FirstName LIKE '%$query%' OR LastName LIKE '%$query%'", $db);
    while(list($FirstName, $LastName)=mysql_fetch_array($result)){
          echo "Result: $FirstName, $LastName <br />";
          }
$add_item = mysql_query("INSERT into name VALUES('bob', '$FirstName')", $db);
$add_item = mysql_query("INSERT into name VALUES('brandon', '$FirstName')", $db);

}
?>

Your query to add names to your database won't work.....check back at post #37.

Also in your form you need to give each field a different name as you currently have them all as "query"

Code:

---

Card #: <input type="text" name="query"><BR><BR>
Total add to card: <input type="text" name="query"><BR><BR>
Total on card: <input type="text" name="query">

I did not know php can fix my file for me.

it can't, you need to make the corrections.

y not?

Just for clarification. Can you post search.php and results.php?
