tlavelle Posted August 13, 2007 Share Posted August 13, 2007 I have been struggling with making a calculator and could use a hand. The concept is a benchmarking calculator where a user: 1. Selects a comparison group and year 2. Enters values per metric 3. Gets a result that shows the benchmarking data vs the suer entered data (basically subtract the best practice cfiled from the user field per record. Here are the pages I have so far page 1 - allows user to select the year and group - gets data from db <html> <head> <basefont face="Arial"> </head> <body> <?php // set server access variables $host = "localhost"; $user = "root"; $pass = ""; $db = "wercbench"; // open connection $connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!"); // select database mysql_select_db($db) or die ("Unable to select database!"); // create query $year_query = "SELECT distinct year FROM userdata"; $industry_query = "SELECT distinct comp_desc FROM comp_desc"; // execute query $year_result = mysql_query($year_query) or die ("Error in query: $query. ".mysql_error()); $industry_result = mysql_query($industry_query) or die ("Error in query: $query. ".mysql_error()); // see if any rows were returned if (mysql_num_rows($year_result) > 0 or mysql_num_rows($industry_result)){ // yes // print them one after another echo"<form method=\"POST\" action=\"uservals.php\" name=\"wercbench1\">"; echo"<table style=\"width: 100%;\" border=\"1\" cellpadding=\"2\" cellspacing=\"2\">"; echo"<tbody>"; echo" <tr>"; echo" <td>Select the comparison year and group then click next"; echo" </td>"; echo" <td></td>"; echo" </tr>"; echo" <tr>"; echo" <td>"; echo" <select name=\"year\">"; while($row = mysql_fetch_row($year_result)) { echo"<option value=\"" .$row[0]. "\">".$row[0]."</option>"; } echo" </select>"; echo" </td>"; echo" <td></td>"; echo" </tr>"; echo" <tr>"; echo" <td>"; echo" <select name=\"industry\">"; while($row = mysql_fetch_row($industry_result)) { echo"<option value=\"" .$row[0]. "\">".$row[0]."</option>"; } echo" </select>"; echo"</td>"; echo" <td></td>"; echo" </tr>"; echo" <tr>"; echo" <td><input type=\"Submit\" value=\"Next\" name=\"wercbench1_next\"></button></td>"; echo" <td></td>"; echo" </tr>"; echo"</tbody>"; echo"</table>"; echo"</form>"; } else { // no // print status message echo "No rows found!"; } // free result set memory mysql_free_result($year_result); mysql_free_result($industry_result); // close connection mysql_close($connection); ?> </body> </html> page 2 - generates for fro user to enter data and submits to calculation page <html> <head> <basefont face="Arial"> </head> <body> <?php include 'index.php'; $useryear=$_POST['year']; $userindustry=$_POST['industry']; // open connection $connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!"); // select database mysql_select_db($db) or die ("Unable to select database!"); // create query $metric_query = "SELECT metric_desc.met_desc, userdata.median, userdata.best_pract FROM metric_desc, userdata where metric_desc.met_key=userdata.met_key and $useryear=userdata.year"; // execute query $metric_result = mysql_query($metric_query) or die ("Error in query: $query. ".mysql_error()); // see if any rows were returned if (mysql_num_rows($metric_result) > 0) { // yes // print them one after another echo "<form action=\"results.php\" method=\"post\">"; echo "<table cellpadding=10 border=1>"; echo "<tr>"; echo "<td>Metric Description</td>"; echo "<td>Average</td>"; echo "<td>Best Practice</td>"; echo "<td>Enter your value here</td>"; echo "</tr>"; while($row = mysql_fetch_row($metric_result)) { echo "<tr>"; echo "<td>".$row[0]."</td>"; echo "<td>" . $row[1]."</td>"; echo "<td>".$row[2]."</td>"; echo "<td><input type=\"text\" name=\"myvalue[]\" value=\"\" /></td>"; echo "</tr>"; } echo "<tr><td colspan=\"3\"> </td><td align=\"center\"><input type=\"submit\" name=\"submit\" value=\"Compare\"></td></tr></table>"; } else { // no // print status message echo "No rows found!"; } // free result set memory mysql_free_result($metric_result); // close connection mysql_close($connection); ?> </body> </html> page 3 - displays tabel containing all benchmark data, user entered data and difference between the 2 this code is nowhere close <html> <head> <basefont face="Arial"> </head> <body> <?php include 'index.php'; $useryear=$_POST['year']; $userindustry=$_POST['industry']; $uservals=$_POST['myval[]']; // open connection $connection = mysql_connect($host, $user, $pass) or die ("Unable to connect!"); // select database mysql_select_db($db) or die ("Unable to select database!"); // create query $metric_query = "SELECT metric_desc.met_desc, userdata.median, userdata.best_pract FROM metric_desc, userdata where metric_desc.met_key=userdata.met_key and $useryear=userdata.year"; // execute query $metric_result = mysql_query($metric_query) or die ("Error in query: $metric_query. ".mysql_error()); // see if any rows were returned if (mysql_num_rows($metric_result) > 0) { // yes // print them one after another echo "<form action=\"results.php\" method=\"post\">"; echo "<table cellpadding=10 border=1>"; echo "<tr>"; echo "<td>Metric Description</td>"; echo "<td>Average</td>"; echo "<td>Best Practice</td>"; echo "<td>Enter your value here</td>"; echo "</tr>"; while($row = mysql_fetch_row($metric_result)) { echo "<tr>"; echo "<td>".$uservals[0]."</td>"; echo "</tr>"; } echo "<tr><td colspan=\"3\"> </td><td align=\"center\"><input type=\"submit\" name=\"submit\" value=\"Compare\"></td></tr></table>"; } else { // no // print status message echo "No rows found!"; } // free result set memory mysql_free_result($metric_result); // close connection mysql_close($connection); ?> </body> </html> My questions are: Is my general approach correct? how do i generate the results for page 3? how do I resubmit the query to generate the table from page 2 without having the user resubmit that form? I am a total n00bie and would love some metoring. Thanks Sorry about the code tag omission...claiming n00bie ignorance Quote Link to comment https://forums.phpfreaks.com/topic/64671-technique-question-creating-a-calculator/ Share on other sites More sharing options...
