Need help with basic php search function...Aren't I a clown

AcidDriver · July 15, 2008

Hi all!

I am realtively new to both php and html, and i was wondering if you could help me out with creating a search function. I am trying to have a html search interface, and then have it pass varaibles into a php search function, going into a mysql database. thanks in advance, im sure it will be a stupid mistake.

HTML Index code

<html>

<head>

<title>Welcome to the HOPE Database</title>

</head>

<body>

<h1>H.O.P.E Volunteer Database Search</h1>

<font class="title">Please enter your database query below.</font>

Search by Name: <input type="text" name="find" /> in

<Option VALUE="fname">First Name</option>

</Select>

</form>

<br>

<a href="volunteer.htm">Input a new volunteer</a>

</body>

</html>

PHP Search Code

<?php

//Displays once search text is run through.

if ($searching =="yes")

{

echo "<h1>Your results: </h1><p>";

//If nothing is entered then return no search text.

if ($find == "")

{

echo "<p>Please enter a search item in the query box</";

exit;

}

// Else, connect to database

mysql_connect("localhost", "root", "") or die(mysql_error()); //Need to setup dedicated H.O.P.E server to link to mySQL, then input user/server info.

mysql_select_db("hope") or die(mysql_error());

//Search for search term once in database.

$data = mysql_query("SELECT * FROM hope WHERE upper($field) LIKE'%$find%'");

//Display results

while($result = mysql_fetch_array( $data ))

{

echo $result['fname'];

echo " ";

echo $result['lname'];

echo "<br>";

echo $result['idnum'];

echo "<br>";

if ($result['grad'] == 0) //This if statement echos back whether or not the volunteer has graduated. 0 for attending, 1 for alumni, 2 for not a student of UM.

{

echo "This volunteer is an attending student.";

}

if ($result['grad'] == 1)

{

echo "This volunteer is an alumni of the University.";

}

if ($result['grad'] == 2)

{

echo "This volunteer is not a student of the University.";

}

echo "<br>";

echo "Volunteer Hours" .$result['volhrs'];

echo "<br>";

}

//NEED TO GET ALL OF MASTER TEMPLATE INFO TO INPUT SEARCH GUIDELINES

//This counts the number or results - and if there wasn't any it gives them a little message explaining that

$matchnum=mysql_num_rows($data);

if ($matchnum == 0)

{

echo "There were no results for you mySQL query.<br><br>";

}

//Echo back what the user searched for:

echo "<b>Searched For: </b> " .$find;

echo "<b>Number of Results: </b> " .$matchnum;

}

?>

can you tell us what it's not doing that it should be? or perhaps an error message?

AcidDriver · July 15, 2008

of course.

Notice: Undefined variable: searching in H:\Documents\My Web Sites\HOPE Search Database\search.php on line 4

Once we fix this one, however, i know there will be more. i think it has something to do with passing the html variables into php...

dannyb785 · July 15, 2008

Did you think to check line 4 on search.php?

if ($searching =="yes")

you haven't set $searching to anything

AcidDriver · July 15, 2008

Of course i checked line 4, not new to programming altogether.

it is in the HTML code, i dont know how to pass it to PHP, unfamiliar to HTML forms, and stuff.

I have tried adding the $, and the same error.

Thanks for tagging along and your help

dannyb785 · July 15, 2008

When you post a form, the page you go to (the action) holds that value in a $_POST array. so in your case, it'd be $_POST['searching'] that you'd be checking to be yes

AcidDriver · July 15, 2008

Thanks, you have helped me on that part, that is useful to know.

Now on to the hard part.

herer is my error message.

Notice: Undefined variable: field in H:\Documents\My Web Sites\HOPE Search Database\search.php on line 21

Notice: Undefined variable: find in H:\Documents\My Web Sites\HOPE Search Database\search.php on line 21

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in H:\Documents\My Web Sites\HOPE Search Database\search.php on line 24

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in H:\Documents\My Web Sites\HOPE Search Database\search.php on line 51

There were no results for you mySQL query.

Notice: Undefined variable: find in H:\Documents\My Web Sites\HOPE Search Database\search.php on line 58

I am going to try and add the $_POST to certain lines to see if it fixes the problem.

AcidDriver · July 15, 2008

It did nothing

dannyb785 · July 15, 2008

do you have phpmyadmin? I would suggest you test our your query to see if it returns any results

so paste this in the sql query

SELECT * FROM hope WHERE upper($field) LIKE'%$find%'

but replace $find with some value that you know it should be able to find. if you return 0 results, then your query is structured wrong.

AcidDriver · July 15, 2008

Error

SQL query:

SELECT *

FROM hope

WHERE upper( $field ) LIKE '%$fname%'

LIMIT 0 , 30

MySQL said:

#1054 - Unknown column '$field' in 'where clause'

dannyb785 · July 15, 2008

Error

SQL query:

SELECT *

FROM hope

WHERE upper( $field ) LIKE '%$fname%'

LIMIT 0 , 30

MySQL said:

#1054 - Unknown column '$field' in 'where clause'

why are you using the upper function? if you're doing a simple search then you'd do WHERE columnname LIKE '%$fname%' but you HAVE to replace $fname with an actual value that is in your database(if you're doing it in phpmyadmin)

AcidDriver · July 16, 2008

I am pretty sure that I have inserted the data into the database, and the search brings up this error.

SQL query:

WHERE fname LIKE '%mike%'

MySQL said:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE fname LIKE '%mike%'' at line 1

fname is the column name, and mike has been inserted in there, I am pretty sure.

AcidDriver · July 16, 2008

Yes, I am using the Browse tab in phpmyadmin to look at the data, and i have an entry. The search function, WHERE fname LIKE '%Jim%', does not work. It gives me an error message telling me to check the syntax.

AcidDriver · July 16, 2008

This project is really important to me, and anyone who helps, I greatly appreciate it.

AcidDriver · July 16, 2008

Anyone, I have this project due by today, and I need help, please.

Here is the error from my search.

My code is posted above. I am really clueless at this point...

AcidDriver · July 16, 2008

can anyone just point me in the general way to solve this problem.

dannyb785 · July 16, 2008

I am pretty sure that I have inserted the data into the database, and the search brings up this error.

SQL query:

WHERE fname LIKE '%mike%'

MySQL said:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE fname LIKE '%mike%'' at line 1

fname is the column name, and mike has been inserted in there, I am pretty sure.

lol dude, when I said "WHERE fname LIKE '%mike%' " I meant to add that to the end of the "SELECT * FROM table" statement.

AcidDriver · July 16, 2008

yea i fixed that lol, the search was working, as well as the search that I created, until i took the table down to upload the complete table...which is giving me issues.

thanks for helping me here
