点击一个 <td> 使用涉及多个表的SQL查询导致自发布事件的元素。 PHP

Question

What I have is a table that is pulled from a database. The goal is that I want to be able to click on any team and have a self posted page produce a table with previous yearly results per row (multiple tables, year by year) and a row of total stats. For example: Click on San Jose and get 2014-2015 stats in 1 row, 2015-2016 in the next row and then a total of all the seasons added up. Not really sure how to implement it. I would love to get some suggestions on the best way to attack this problem. Link To My Project
Here is some of my code, so you can see how I am doing it so far.

$query = "SELECT * FROM standings2015_2016 WHERE confid='2' ORDER BY pts DESC, losses ASC, otl ASC, gf-ga DESC";
        $result = $db->query($query);
        echo "<h3>Western Conference</h3>";
        echo "<table class='table sortable'>";  
        echo "<tr class='TableHeaders'>";
        echo "<td class='hover'>Place</td>";
        echo "<td class='hover'>Team</td>";
        echo "<td class='hover'>Wins</td>";
        echo "<td class='hover'>Losses</td>";
        echo "<td class='hover'>OTL</td>";
        echo "<td class='hover'>Points</td>";
        echo "<td class='hover'>GF</td>";
        echo "<td class='hover'>GA</td>";
        echo "<td class='hover'>+ / -</td>";
        echo "</tr>";   

        $i = 0;
        foreach ($result as $row) {
        $i++;
        $plusMinus = ($row['gf'] - $row['ga']); 
          echo "<tr>";
            echo "<td>";
            echo $i;
            echo "</td><td class='hover2'>";
            echo stripslashes($row['name']); 
            echo "</td><td>";
            echo stripslashes($row['wins']);
            echo "</td><td>";    
            echo stripslashes($row['losses']);  
            echo "</td><td>";    
            echo stripslashes($row['otl']); 
            echo "</td><td>";    
            echo stripslashes($row['pts']);
            echo "</td><td>";
            echo stripslashes($row['gf']);
            echo "</td><td>";
            echo stripslashes($row['ga']);
            echo "</td><td>";
            echo $plusMinus;
            echo "</td>";
         echo "</tr>";
          }
        echo "</table>";

So echo stripslashes($row['name']); is the team name I want to click on. Can this be done with an onclick event to prompt a query and a self post?

Answer 1

In order to do what you want, we can use jQuery and Ajax .

First is to download jQuery here .

Then create a link element for each team name that has class and data-artid tag:

echo '<a href="#" class="teamname" data-artid="'.$row["teamid"].'">'.stripslashes($row['name']).'</a>'; 

Then create the script:

<script src="jquery-1.9.1.min.js"></script> <!-- REPLACE NECESSARY JQUERY FILE DEPENDING ON THE VERSION YOU HAVE DOWNLOADED -->
<script type="text/javascript">

  $(document).ready(function(){ /* PREPARE THE SCRIPT */
    $(".teamname").click(function(){ /* WHEN A TEAM IS CLICKED */
      var elem = $(this); /* STORE THE CLICKED TEAM */
      var teamid = elem.attr("data-artid"); /* GET THE ID OF THE CLICKED TEAM NAME */

      $.ajax({ /* PREPARE THE AJAX */
        type: "POST", /* METHOD TO BE USED TO PROCESS THE PASSED DATA */
        url: "action.php", /* THE PAGE WHERE THE DATA WILL BE PROCESSED */
        data: {"teamid": teamid}, /* THE DATA WE WILL PASS */
        success: function(result){
          $("#content").html(result); /* WE WILL SHOW THE RETURNED DATA TO YOUR CONTENT DIV */
        } /* END OF SUCCESS */

      }); /* END OF AJAX */
    });
  });

</script>

And for your action.php, which will process the passed on data using Ajax:

<?php

  /* INCLUDE YOUR DB CONNECTION HERE */

  if(!empty($_POST["teamid"])){

    $tr = '
          <table class="table sortable">
            <tr class="TableHeaders">
              <td class="hover">Team</td>
              <td class="hover">Wins</td>
              <td class="hover">Losses</td>
              <td class="hover">OTL</td>
              <td class="hover">Points</td>
              <td class="hover">GF</td>
              <td class="hover">GA</td>
            </tr>
          ';

    $result = $db->query("SELECT name, wins, losses, otl, pts, gf, ga FROM standings2014_2015 WHERE teamid = '".$_POST["teamid"]."'");
    foreach ($result as $row) {
      $tr .= '
             <tr>
               <td>'.$row["name"].'</td>
               <td>'.$row["wins"].'</td>
               <td>'.$row["losses"].'</td>
               <td>'.$row["otl"].'</td>
               <td>'.$row["pts"].'</td>
               <td>'.$row["gf"].'</td>
               <td>'.$row["ga"].'</td>
             </tr>
             ';
    } /* END OF LOOP */

    $tr .= '</table>';

    echo $tr; /* RETURN THIS TO AJAX */

  } /* END OF NOT EMPTY teamid */

?>

Answer 2

You can assign an ID to each one of the teams in your database and then use that ID to pull the information in one php file. In that file you can just get the ID perform the query search and display the information in a different page.

In the index.php where you display all the teams you can add a link to the team.php.

 echo "<a href=\"team.php?Id=".$team['Id']."\">";

team.php

    if (isset($_GET['Id']) && is_numeric($_GET['Id'])) 
    {
    // Perform database query
    $teamID = mysql_escape_string($_GET['Id']);

    // Assign the query to a variable
    $query = "SELECT name, wins, losses, otl, pts, gf, ga FROM standings2014_2015 WHERE Id=".$teamID.";";
    $result = $conn->query($query);

    // If the user exists
    if ($result) 
    {
    while ($team = $result->fetch_assoc()) 
    {
       echo $team["name"];
       echo $team["wins"];
       ....
// Display the information in the table
}
}

Answer 3

I suggest this code:

For standings.php modify this:

 echo stripslashes($row['name']); 

by:

 echo "<a href=\"standings.php?name=".stripslashes($row['name'])."\">";

Then standings.php should view like this:

    if (isset($_GET['name']) && !is_empty($_GET['name'])) 
    {

    $kname = mysql_escape_string($_GET['name']);

    $query = "SELECT name, wins, losses, otl, pts, gf, ga FROM standings2014_2015 WHERE name=".$kname.";";
    $result = $db->query($query);

    if ($result) 
    {  echo "<table class='table sortable'>";  
       foreach ($result as $row) 
       {
         $tr .= '
           <tr>
             <td>'.$name.'</td>
             <td>'.$wins.'</td>
             <td>'.$losses.'</td>
             <td>'.$otl.'</td>
             <td>'.$pts.'</td>
             <td>'.$gf.'</td>
             <td>'.$ga.'</td>
           </tr>
           ';
         echo $tr;

       }
       echo "</table>";  
    }

   }else{ 
     //YOUR ACTUAL CODE
   }
