PHP - Display Results Of Query By Clicking A Hyperlink

First off, let me say that this will not be a public use site.  We want to create a site that allows us to run queries in our database; this way we don't need to log into the MySQL server when ever we want to run a query.

Basically, I am trying to create something as simple as a form with a text-input and a submit button.  In this text-input, we will write a query (such as SELECT * FROM xxxx).  When we hit submit, we would like to have the MySQL table printed out in a large textbox below.

Our database has multiple tables, so something that works across the entire database seamlessly is key.

Has anyone ever made anything like this?  Is there another way to go about this?  We really just want an easy way to run queries on the go.

Thanks in advance to anyone who replies!

Say a user puts in a support request, and for every request it generates a unqiue string, and enters it into the database.

Ok, now say there is a text field, when the user enters their unique string and it finds a match, it displays the data along with it.

How can I accomplish this? Im kind of new to mysql, but I know basic SQL.

Would be great if somebody could point me in the right direction!

Thanks

In an .html, before : <!-- BEGIN myquery -->

I need to stop output and check the content of "myquery"

Is there a command for that ?

Thank You.

I have the following code that searches my database and displays results in a table:

$fields = array("field1", "field2", "field3")
$cols   = implode (', ', $fields); 

$result= mysql_query 
(" SELECT $cols FROM tablename  WHERE ................... ");

if (!$result) {die('Could not search database: ' . mysql_error());}

if($result)
{   
    
    if(mysql_num_rows($result) == 0)
    {
        return "Sorry. No records found in the database";                       
    }
    else 
    {
        $table = "<table border='1' cellpadding='5' cellspacing='5'>";
        while($arr = mysql_fetch_array($result, MYSQL_ASSOC))
        {
            $table .= "\t\t<tr>\n";
            foreach ($arr as $val_col) 
            {
                $table .= "\t\t\t".'<td>'.$val_col.'</td>'."\n";
            }
            $table .= "\t\t</tr>\n";  
        }
        $table .= "</table>";
        echo $table;
    }
    mysql_free_result($result);       
}

As you can see each of the MySQL table fields specified by $fields is displayed in a new column in the html table.
I want to change this so that e.g. "field3" is displayed in a new row instead.

So, instead of the html table looking like:

| "field1-result1" | "field2-result1" | "field3-result1" |
| "field1-result2" | "field2-result2" | "field3-result2" |
| "field1-result3" | "field2-result3" | "field3-result3" |

I want it to look like:

| "field1-result1" | "field2-result1" | 
| "field3-result1" |                          |
| "field1-result2" | "field2-result2" |
| "field3-result2" |                          |
| "field1-result3" | "field2-result3" |
| "field3-result3" |                          |

I guess this is quite straightforward, but I can't work it out! Pls help!

Thanks.

I'll walk you first through what is working:

<?php echo($user['biz_site'] != '' ? "<h4>Web Site</h4>" . $user['biz_site'] : ""); ?>


In a results page, the code renders something that looks like:
Quote

Web Site
http://www.somecoolsite.com


What I'd like instead is something like this:
Quote

Web Site
Visit Site


...where the "visit site" links to the site.  I'm trying to address a problem of some sites, especially government sites, having 75+ character-long addresses, which messes up the finite space I have allotted for site addresses.

Everything I've tried thus far has rendered blank white pages.

(the original code posted up top does not produce a hyperlink)

So I am trying to execute an sql query by clicking a button or a link. Ultimately I want users to be able to click the "Fav" button and it then fades into "Added to favorites!" (I am building a favorite system which first collects data on page load like userid and itemid and then it needs to send it to the DB after a button is clicked)

The fade and stuff is not the most important part now (although a tip on doing that would be awesome) but the most important part is how to get this functional:
PHP Code:
        <?php 
    // Start Favorite System!
        $user =& JFactory::getUser();
        $userid = $user->id;
        if ($userid == 62) {
            echo "userID: ".$userid."<p />";
            if ($user->guest) {echo "You are a guest<p />";}
            $itemid = $this->item->id;
            echo "itemID: ".$itemid."<p />";
            $catid= $this->item->category->id;
            echo "catID: ".$catid."<p />";
            
            $query = "INSERT INTO jos_k2_fav_xref (userID, itemID, catID) VALUES ('$userid', '$itemid', '$catid')";

            // Need a way to make this into a button
            $run = mysql_query($query) or die(mysql_error());
        } else {}


        ?>
Currently all the values get stored in the DB as the page is loaded. I however want to be able to click on something to execute that query how do i do that? I read a bunch of stuff on javascript and ajax but it got me nowhere...

Help is greatly appreciated!

Hello all,   Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).   The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).   Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:   In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).   I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.   Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.   So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:   1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red. 2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red. 3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.   Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.   Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.   Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.   Cheers guys!

I am brand new to PHP but, after using W3 Schools,  can retrieve a record from a MySQL database using php & SQLi.    I have a page with a list of between 20 and 30 items down one side and a panel on the other. When a user clicks a list item I want to display the details of the clicked item in the panel. The details a Program (text), Convenor (text), Dates (text), Times (Text), Location (text), Notes (Text large).    The details are stored in a MySQL Database 'Documents', in a table 'Programs' and I would like to put the details into text boxes in the panel.   Could you point me to some info on doing this please? Thanks  

Hello, I am new to the board and PHP. I created a simple store locator app with PHP. It pulls the info from a database. I want to  take the website field from the table, once it is returned from the query, and have it print out a a hyperlink.
Please help.

Thanks, I have posted most of the relevant code.


<?php   if (isset ($stores)) {     if (!empty ($stores)) {       
   echo '<p><strong>' . count ($stores) . ' results were found.</strong></p>';     foreach ($stores as $value) {         
   echo '<p><strong>' . $value['name'] . '</strong><br />';       
   echo $value['address'] . '<br />';       
   echo $value['town'] . ', ' . $value['state'] . ' ' . $value['postal'];     
   echo '&nbsp;<a target="_blank" href="http://maps.google.com/maps?q=',
            $value['address'], ' ', $value['town'], ', ', $value['state'], ' ',
            $value['postal'],'">Map this location</a><br />';       
   echo 'Phone: ' . $value['phone'] . '<br />';
   echo 'Website: ' . $value['website'] .  '<br />'; 
   echo 'Email: ' . $value['email'] . '<br />';   
   echo 'Hours: ' . $value['hours'] ;

Can someone please give me some ideas as to what might be wrong with this query...I keep getting no result and am echoing $count for debugging (and usernames and passwords) but get nothing for $count (expecting a 0 or a 1) or $dbusername or $dbpassword

$sql="SELECT * FROM `users` WHERE `User name` = '$fusername' and `Password` = '$fpassword'";
$result=mysql_query($sql);

$dbusername=mysql_result($result,0,"User name");
$dbpassword=mysql_result($result,0,"Password");

echo $dbusername;
echo $dbpassword;


// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $fusername and $fpassword, table row must be 1 row

echo $fusername;
echo $fpassword;
echo $count;

if($count==1){                                               (This is where I keep going to the else)

quick question,
I have this code that returns over 100 buttons:
Code: [Select]
        <?php
// Query member data from the database and ready it for display
$sql = mysql_query("SELECT * FROM products");
while($row = mysql_fetch_array($sql)){
$product = $row["product"];
$id =$row["id"];
$price =$row["price"];

?>
    <div id="products">
      <form action="" method="POST" name="myform<?php echo $id; ?>" class="myform<?php echo $id; ?>">
        <input type="hidden" name="hiddenField" class="hiddenField" value="<?php echo $product; ?>" />
        <input type="hidden" name="hiddenField2" class="hiddenField2" value="<?php echo $id; ?>" />
        <input type="hidden" name="hiddenField1" class="hiddenField1" value="<?php echo $price; ?>" />
      <input type="submit" name="submit" class="submit" value="<?php echo $product; ?>" style="background-color:lightgreen; height:50px; width:100px;">   </form>
    </div>   
<?php

}

What I would like is for the buttons to form columns of nine. ie 9 buttons in a column then a new column form....  how do I do this?

Hi, say I have a query like so:



foreach($_REQUEST['r'] as $position => $row) 
    
  {   $row = implode("', '",$row);
      $result = mysql_query("Insert into player_stats (position,shirt_number,player_id,goals,cards,substituted,used_sub,injury,season,report_id)   
                             values('$position','$row','$currentSeason','$report_id')");
  }


How do I print the results of that query to my Browser for each time?

Thanks

this is my query code
Code: [Select]
<?php
$wsi_query = "(SELECT * FROM (SELECT a.no_Yards AS 'yards', a.Day_Swam AS 'date', a.Season AS 'season', (SELECT sum(no_yards) FROM swimming WHERE Season = '$ws') AS 'totalyards', (SELECT AVG(no_Yards) FROM swimming WHERE Season = '$ws') AS 'avg', (SELECT count(*) FROM swimming WHERE Season ='$ws') AS 'timelaps', (SELECT 1 + count(*) FROM swimming b WHERE b.no_Yards > a.no_Yards AND Season = '$ws') AS hrank, (SELECT 1 + count(*) FROM swimming b WHERE b.no_Yards < a.no_Yards AND Season = '$ws') AS lrank FROM swimming  AS a) AS x WHERE Season = '$ws' )";
$wsi_result = mysql_query($wsi_query) or die("Query failed ($wsi_query) - " . mysql_error());
$wsi_row = mysql_fetch_assoc($wsi_result);
?>
what it should do is output both the min and the max values like this
Code: [Select]
<?php
while ($mm_wsi_row = mysql_fetch_assoc($wsi_result)){
if ($mm_wsi_row['hrank'] == 1){
if ($mm_wsi_row['date'] == "0000-00-00"){$dayswam = "";}else{$dayswam = $mm_wsi_row['date'];}
echo "<tr>";
echo "<td style='background-color:#F90'>Max Length:</td>";
echo "<td>" . number_format($mm_wsi_row['yards']) . "</td>";
echo "<td>" . $dayswam . "</td>";
echo "</tr>";
}
 if($mm_wsi_row['lrank'] == 1){
if ($mm_wsi_row['date'] == "0000-00-00"){$dayswam = "";}else{$dayswam = $mm_wsi_row['date'];}
echo"<tr>";
echo "<td style='background-color:#F90'>Min Length:</td>";
echo "<td style='background-color:#FF9'>". number_format($mm_wsi_row['yards']) . "</td>";
echo "<td style='background-color:#FF9'>" . $dayswam . "</td>";
echo "</tr>";
}
?>
the problem is that it doesn't work right all the time for some it just shows the min while others it just shows max I've tested the query in MySQL workbench so i know that that is working right but idk why it works right for some and doesn't work for others
