    Hello All, I've been taking a PHP class for the past 7 weeks and are getting a little hard. This is the first time I have ever messed with PHP and i just don't seem to get it. I have the following assignment:

    -Name a script solution09.php
    -Wtihin the script construct a SELECT statement which will query the "expenses" table for all the purchases made.
    -Process the resulting recordset with a while loop which will create a separate line for each expense.
    -On each line display the category, date, and amount of expenses.
    -Create an HTML form , provide the visitor with an input box so they may use it to enter an expenses ategory (THIS IS DONE)
    -Modify the schript so that it retrieves the value entered by the visitor
    -Modify the SELECT statement created within the script so thatit includes a WHERE clause which will test to make sure that the category column is equal to the valueentered by the visitor.

    Now, I think I got the script pretty much done EXCEPT for hte last two steps. I don't understand what im supposed to do or where Im supporsed to start. Any help is greatly appreciated :cryin:

    sorry i forgot to post my script:
    $connection=mysql_connect ("localhost", "spike", "9sj7En4");
    if (!$connection)
    die  ('Could not Connect: '. mysql_error());
    mysql_select_db ("My_DB", $connection) or die (mysql_error());
    $result = mysql_query ("SELECT * FROM Expenses") or die (mysql_error());
    echo "<table  border='2'>
    <th>Dollar Amount</th>
    while ($row= mysql_fetch_array ($result))
    echo  "<tr>";
    echo  "<td>" .$row ['Category'] ."</td>" ;
    echo  "<td>" .$row ['Date']  ."  </td>";
    echo  "<td>" .$row ['Dollar Amount'] . "  </td>";
    echo  "</tr>";
    echo "</table>";
    mysql_close ($connection);

    =mysql_connect ("localhost""spike""9sj7En4");
    if (!
    die  (
    'Could not Connect: 'mysql_error());
    mysql_select_db ("My_DB"$connection) or die (mysql_error());
    // they did not click the button
    $result mysql_query ("SELECT * FROM Expenses") or die (mysql_error());
    "<table  border='2'>
    <th>Dollar Amount</th>
    while (
    $rowmysql_fetch_array ($result))
    "<td>" .$row ['Category'] ."</td>" ;
    "<td>" .$row ['Date']  ."  </td>";
    "<td>" .$row ['Dollar Amount'] . "  </td>";
    // the form was submitted
    // retrieve all the values from the form here
    mysql_close ($connection);
    Now, you only have to make sure the button name in the form
    is 'submit_button' for example :

    <form action="" method="post">
    <input type="submit" value="GO" name="submit_button" />
    Considering your new to PHP, I want to let you know using single-quotes instead
    of double-quotes speeds up your script.
