PHP - Display Certain Page If No Results From Query?

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.

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!

Code: [Select]
The form below is meant to retrieve the named attribute of a form input called "limitedtextfield" , along side the current date and store those values in a database.  The form contains some javascript which can be disregarded for this particular problem.
[code]
<form name="mymind" style= "position:relative;left:40px;" action="insert_status.php" method="post">

<input  name="limitedtextfield" type="text" onKeyDown="limitText(this.form.limitedtextfield,this.form.countdown,55);"

onKeyUp="limitText(this.form.limitedtextfield,this.form.countdown,55);" maxlength="55"><br>

<font size="1">(Maximum characters: 55)<br>

You have <input readonly type="text" name="countdown" size="3" value="55"> characters left.</font>

<input type="hidden" name="submitted" value="TRUE"/>

<input style="position:relative;left:0px;bottom:0px;" type="submit" name="submit" value="Submit!" />

</form>




Here is the php script that processes the form. What it is meant to do is search the database and if no record is found for the authenticated member,  input the relevant values into the database.  If a record is found, it should update the record.  Well every time I hit the submit button, all I get is a blank page.  Any clue as to what is going wrong?

PS:  I checked the database and no values got inserted. Code: [Select]
<?php

//address error handling

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);


//authenticate user
require('auth.php');

//Connect to database
require ('config.php');




if (isset($_POST['submitted'])) {

$query = "SELECT* FROM publications WHERE member_id ='".$_SESSION['id']."' AND cartegory='status'";
        $result = @mysql_query($query);
        $num = @mysql_num_rows($result);
       
        if ($num> 0) {

$update = mysql_query("UPDATE publications SET publication = '{$_POST['limitedtextfield']}' WHERE member_id = '".$_SESSION['id']."' AND cartegory = 'status'"); 

header("Location: member.php");
            
        } else {



         $query = "INSERT INTO publications ( member_id, publication, cartegory, pub_date)

  VALUES ( '{$_SESSION['id']}','{$_POST['limitedtextfield']}', 'status', NOW() )";


header("Location: member.php");
            

}

}



?>
 

I have a search page and everything works fine but I would like to add the latest 10 rows to the page so there is something to look at or click on before the user searches.

The page is at: www.giantstridedives.com/locations. You can see that it's pretty boring. Hit submit and you'll see the entries so far (only 3 right now). I'd like to have the latest 10 display there by default but then when a user searches they are replaced by the search results. Make sense?

Here's the code I'm using for the search:

Code: [Select]
<?php
if (isset($_POST['submit'])) {

require_once('dbconnection.php'); 
mysqli_select_db($conn, $dbname); 
$searchterm = $_POST['search']; 
$searchterm = strip_tags($searchterm);
$searchterm = trim ($searchterm);
$q ="SELECT * FROM locations WHERE loc_name LIKE '%" . $searchterm . "%' AND loc_approved != '0'"; 
$r = mysqli_query($conn, $q) or die(mysql_error($q)); 
$row = mysqli_fetch_assoc($r); 
$rowcount = mysqli_num_rows($r);
}
?>

<h1>Search for Scuba Dive Locations</h1>
<form id="searchform" name="searchform" method="post" action="index.php"> 
    <input type="text" name="search" id="search_bar" />
    <input type="submit" name="submit" id="submit" value="Submit" /> </form>
<span style="color: #333;">Search for the name of the location, ie: Devils Den or USS Oriskany.</span><br />   


<?php 
if (isset($_POST['submit'])) {

if ($rowcount == 0)  
{
echo "Sorry, but we can not find an entry to match your query: <strong>$searchterm</strong>";
}
else { //this tells the table below to display since $totalRows_Products_res is not 0
?>
<table style="font-size: 14px;" border="0" width="650">
 <tr>
  <td colspan="6"><p>You searched for <strong><?php echo $searchterm; ?></strong>. Results are displayed below.</p></td>
 </tr>
<tr>
  <td><strong>Location Name</strong></td>
  <td><strong>City</strong></td>
  <td><strong>State</strong></td>
  <td><strong>Depth (ft)</strong></td>
  <td><strong>Fees</strong></td>
  <td><strong>Gear Rentals</strong></td>
  <td><strong>Map</strong></td>
 </tr>
 <?php do { ?>
  <tr>
   <td><a href="loc_details.php?loc_id=<?php echo $row ['loc_id']; ?>">
<?php echo $row ['loc_name']; ?> </a></td>
<td><?php echo $row ['loc_city']; ?></td>
<td><?php echo $row ['loc_state']; ?></td>
<td><?php echo $row ['loc_depth']; ?></td>
<td>$<?php echo $row ['loc_fee']; ?></td>
<td><?php if($row['loc_gear'] == 1) {
echo 'Yes';
} else { echo 'No'; } ?></td>
<td><a href="http://maps.google.com/maps?q=<?php echo $row ['loc_lat'];?>,<?php echo $row ['loc_lon'];?>" target="_blank">View Map</a></td>
   </tr>
  <?php } while ($row = mysqli_fetch_assoc($r)); ?>
</table>
<?php 
mysqli_free_result($r); 
} // this closes out results else
}
?>

I figure I can use the below query to get the results.
Code: [Select]
select * from table WHERE id >  ((SELECT MAX(id) from table) - 10);I'm just not sure how I can display them by default and then have them be replaced by the search results.  Anyone have any ideas for me? As always I appreciate the help as I continue to learn this beast.

Good day and Merry Christmas to all,

I just spent a good time of my christmas eve trying to figure out this problem. I hope one of you santas would be so kind as to help me with it.

First off I have two tables; employee and employee_works both connected via employee_id key.

Basically I have a parent window we'll call parent.php.
inside the parent page is a search button that once clicked will open a child window we'll call child.php

inside the child page is a list, lets say employees with name, employee_id, etc.

My main concern is this:
How do I populate parent.php based off the employee selection I made in the child window.

Example:
-Access parent.php
-Click on search
-Click on [ID: 004] [NAME: JOHN SMITH] [PHONE: 1233456] [DATE HIRED: JULY 16, 1992] <---format of a row in child.php
-child.php automatically closes and parent.php now shows all data from employee_works with the employee_id = 004

Is this even possible? I know this is vary vague and would be willing to explain more if needed. My website is built mostly on javascript and php.

I wrote the page below to display a member's area of a website.  The page is a mix of html and php code.  the first part of is a block of php, which authenticates the user and displays the header.  The middle part is a block of html which contains the bulk of the page.  Embedded in this block of html are two sections of php, the first of which is supposed to display a user uploaded picture, enclosed in div tags, and the second of which, prints out the user's first name, from the database.   The end of the script is a line of php that displays the footer.  Now the page displays correctly when the section of php that contains the select query for displaying the picture(starting line 104) is omitted.  But once I include that section, all i see is a blank page.  Why is that section of php problematic? What can be done to fix it?  Here is the data for the full page.  Thanks for any help.

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!

What would be the correct way to close a mysql query?

At current the second query below returns results from the 1st query AND the 2nd query
The 3rd query returns results from the 1st, 2nd and 3rd query.
 etc etc.

At the moment I get somthing returned along the lines of...

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?

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

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

If ($_GET['CODE'] == '1') {
    $ThreadID = mysql_escape_string($_GET['threadid']);
    $ForumID = mysql_result(mysql_query("SELECT forum_id FROM ".FORUM_THREADS." WHERE thread_id='{$ThreadID}'", $db), 0, 'forum_id');
    $PostText = mysql_escape_string($_POST['replytext']);
    $IP = $_SERVER['REMOTE_ADDR'];
    $PostQuery = "INSERT INTO ".FORUM_POSTS." (`user_id`, `thread_id`, `post_text`, `forum_id`, `ip_address`, `timestamp`) VALUES ('{$memid}', '{$ThreadID}', '{$PostText}', '{$ForumID}', '{$IP}' , CURRENT_TIMESTAMP)";
    $PostRes = mysql_query($PostQuery, $db);


For some reason whenever this query goes through, it also adds a blank result using all the same information but without any $PostTest so essentially it does query:

Code: [Select]
INSERT INTO ".FORUM_POSTS." (`user_id`, `thread_id`, `post_text`, `forum_id`, `ip_address`, `timestamp`) VALUES ('{$memid}', '{$ThreadID}', '', '{$ForumID}', '{$IP}' , CURRENT_TIMESTAMP)

This is the only query that does this part of the code and I can't see why it is adding 2 queries.

FORUM_POSTS = constant containing table name.

Below is my query which works fine:

 $query = "
          SELECT st.CourseId, c.CourseName, st.Year, st.StudentUsername, st.StudentForename, st.StudentSurname,
          s.ModuleId, m.ModuleName, m.Credits, s.SessionId, s.SessionWeight, gr.Mark, gr.Grade
          FROM Course c
          INNER JOIN Student st ON c.CourseId = st.CourseId
          JOIN Grade_Report gr ON st.StudentId = gr.StudentId
          JOIN Session s ON gr.SessionId = s.SessionId
          JOIN Module m ON s.ModuleId = m.ModuleId
          WHERE
          (st.StudentUsername = '".mysql_real_escape_string($studentid)."')
          ";

Below is my results outputted by using php:

    Course: INFO101 - Bsc Information Communication Technology Year: 3
    Student: Mayur Patel (u0867587)
   
    Module: CHI2550 - Modern Database Applications
    Session: AAB 72 (A)
   
    Course: INFO101 - Bsc Information Communication Technology Year: 3
    Student: Mayur Patel (u0867587)
   
    Module: CHI2513 - Systems Strategy
    Session: AAD 61 (B)
   
    Course: INFO101 - Bsc Information Communication Technology Year: 3
    Student: Mayur Patel (u0867587)
   
    Module: CHI2550 - Modern Database Applications
    Session: AAE 67 (B)

How do I display it using php so that it only shows Course details and Student details only once, it will show each module in the course only once and shows each session being below each module it belongs to:

The output from above should look like this in other words:

     Course: INFO101 - Bsc Information Communication Technology Year: 3
        Student: Mayur Patel (u0867587)
       
        Module: CHI2550 - Modern Database Applications
        Session: AAB 72 (A)
        Session: AAE 67 (B)
       
        Module: CHI2513 - Systems Strategy
        Session: AAD 61 (B)


PHP code to output the results:

    $output1 = "";
   
            while ($row = mysql_fetch_array($result)) { //$result is the query
              
        $output1 .= "
             <p><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Year:</strong> {$row['Year']}<br/>
              <strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})
              </p>";
             
        $output1 .= "     
        <p><strong>Module:</strong> {$row['ModuleId']} - {$row['ModuleName']} <br/>
              <strong>Session:</strong> {$row['SessionId']} {$row['Mark']} ({$row['Grade']})
              </p>";
                }
               
                echo $output1;

Thank You
