PHP - Some Jquery Code Is Not Working With Appending Of Table Rows

Hi, I have an app that access a MySQL database via a php script.
I noticed that INSERT was returning error but the data was being recorded successfully.
I finally traced the problem to be related with the line 
echo $conn->affected_rows;   

For some reason when it is an SQL INSERT it returns -11 but as I said the INSERTS executes successfully.

The app requesting the service sends in sequence:

char* txtSQL[]={"INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)",
                            "UPDATE activity set value=333 where value=130",
                            "SELECT sum(value) from activity where mac='a9c4952de6b4'",
                            "DELETE from activity WHERE value=333"};

I set a monitor to check what was being returned and got:

query=INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)
HttpResponse:  -   httpResponseCode: -11

HttpResponse:  -   httpResponseCode: -11
query=INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)
HttpResponse:  -   httpResponseCode: -11
query=INSERT INTO activity (mac,jd,date,time,area,type,value) VALUES ('a9c4952de6b4',2458454,'2018-12-01','10:22','Area0002','h',130)
HttpResponse:  -   httpResponseCode: -11
query=UPDATE activity set value=333 where value=130
HttpResponse: 4 *   httpResponseCode: 201   -------------------------------------->As can be seem the INSERTS above returned error but worked OK
query=SELECT sum(value) from activity where mac='a9c4952de6b4'
HttpResponse: 1379 *   httpResponseCode: 200
query=DELETE from activity WHERE value=333
HttpResponse: 4 *   httpResponseCode: 201

Any help will be much appreciated.

I wonder if anyone can help me, I have a MySQL table of football teams (team_name; link; description; rival_1; rival_2; rival_3;) where each 'team_name' has its own page with the relevant information from the table and is named as the link field from the table. Within each team page I also want to display the rival_1,2 and 3 teams with links to their pages. I know how to just display the information but am struggling with picking up the link from the relevant row in the table. Is this possible or would I be better off just placing a <a href> link around each rival team when I enter it into the MySQL table??

I hope this makes sense, any help would be very much appreciated. Thanks

I want to delete rows in a table of my database using check-box.
Here are my codes below:

Code: [Select]
<?php
$con = mysql_connect('localhost', 'root', '') or die ('Connection Failed');
mysql_select_db('img', $con) or die ('Connection Failed');
$display = mysql_query("SELECT * FROM photos WHERE email='$lemail'");
echo '<input type="submit" value="Delete" name="del"/>';
echo "<table>
<tr>
<th>#</th>
<th>Images</th>
<th>Image description</th>
<th>Delete</th>
</tr>";
while($row = mysql_fetch_array($display))
{
echo "<tr>";
 echo "<td>".$row['img_ID']."</td>";
  echo "<td><img src='folder/".$row['imaged']."' alt='alt text' width='100' height='100' class='thumb'/> </td>";
echo "<td>".$row['image_description']."</td>";
echo '<td><input type="checkbox" name="delete[]" value="'.$row['img_ID'].'"/></td>';
echo "</tr>";
}
echo "</table>";
echo "</form>";
if (isset($_POST['delete'])) {
$del = $row['img_ID'];
for($i=0;$i<count($_POST["delete"]);$i++)
{
if($_POST["delete"][$i] != "")
{
$str = "DELETE FROM photos WHERE img_ID='$del' ";
mysql_query($str);
echo "Record Deleted.";
}
} 
}
mysql_close($connect);
?>
Here are the problems:

1/ Not working at all, I mean no image is being deleted
2/ At then end, I display a message that the record has been deleted, but if I check multiple checkbox, it keeps writing the message "Records deleted" multiple times

My images are stored in a folder while its details in database...

Help, thank you 

The table is:

next       next_id        id

0              2               1
1              3               2
0              4               3
0              1               4



The form:

<?php 
include 'dbc.php';
page_protect();

if(!checkAdmin()) {
header("Location: login.php");
exit();
}

  if($_POST['doSubmit'] == 'Create') {

list($next_id) = mysql_fetch_row(mysql_query("select next_id from users where id='$id'"));

mysql_query("update users set approved='1' where id='$id'");

mysql_query("update users set next='1' where id='$next_id'");

mysql_query("update users set next='0' where id='$id'");

list($to_email) = mysql_fetch_row(mysql_query("select user_email from users where id='$id'"));

$ret = $_SERVER['PHP_SELF'] . '?'.$_POST['query_str'];  
 header("Location: $ret");
 exit();

$message = 
"Hello \n

";

@mail($to_email, "Aaaaack", $message,
    "From: \"Lobo\" <auto-reply@$host>\r\n" .
     "X-Mailer: PHP/" . phpversion()); 

 
}

I am sorry if this is posted in the wrong place!  Here to learn.  Thank you for any clues!

I know how much you guys hate people asking for help without any starting code but I'm not even sure how to start this..

I want a script to read this page and count all the admins and referees.

If anyone is willing to help, here's a sample of the html code:
Code: [Select]
<div class="boxInner"><h3>Arena Referees</h3><table class="list"><thead><tr><th style="width:16px;"></th><th style="width:150px;">Name</th><th style="width:300px;">Position</th><th style="width="150px;">Gamertag</th></tr></thead><tbody><tr><td><a href="http://gamebattles.com/profile/GottaHaveFaith78"><img src="http://media.gamebattles.com/icons/16/profile.png" class="icon16" /></a></td><td class="alt1">Faith</td><td><b>Head Referee</B></td><td class="alt1">GB CombatBarbie</td></tr><tr><td class="alt2"><a href="http://gamebattles.com/profile/Jack.-"><img src="http://media.gamebattles.com/icons/16/profile.png" class="icon16" /></a></td><td>Jack</td><td class="alt2"><b>Asst. Head Referee</b></td><td>Get Jacked x</td></tr><tr><td><a href="http://gamebattles.com/profile/amghawk"><img src="http://media.gamebattles.com/icons/16/profile.png" class="icon16" /></a></td><td class="alt1">Mike</td><td><b>Asst.

I'm just wondering how I could even count them.

Any help will be appreciated, thanks.

Hi, I'm very new to these forums and php alike.  I've been working on this bit of code for weeks now.  I've written numerous versions and made endless revisions; trying pieces from many similiar source and well, it's still not quite working out for me.

The form I've been trying to finish will have multiple rows. The user will input values specific to each row, but I'm trying to make it so that each row is synonymous with each other in regard to the database table. Like an order form, an inventory form, or a roster. I'd really like to make this code work out because I can think of numerous applications for it's use. I'm sure others could use it for even more.

So, as you see; the html code represents the table that contains the form. Currently, I only have five of these rows in the form, but would like for anybody using the code to be able to add in code for as many rows in the table as needed.
Code: [Select]

In the php script I've tried using the count, loop, if, several others functions to try to get it to insert all the completed rows from the form into the table but just can't seem to get it to work out.  Anyways, here's a representation of what i'd like to achieve.  Not necessarily the code I've written trying to accomplish this, I'd have to upload a book if that were the case.

<?php 
ini_set('display_errors','On'); 
error_reporting(E_ALL); 

$host="localhost"; // Host name  
$username="root"; // Mysql username  
$password="password"; // Mysql password  
$db_name="testing"; // Database name  
$tbl_name="test_multiple"; // Table name 

// Connect to server and select databse. 
mysql_connect("$host", "$username", "$password")or die("cannot connect");  
mysql_select_db("$db_name")or die("cannot select DB"); 

//declarations 
$vendor = $_POST['vendor']; 
$description = $_POST['description']; 
$quantity = $_POST['quantity']; 
$price = $_POST['price']; 

// Check if button name "Submit" is active, do this  
$sql1="INSERT INTO $tbl_name (vendor, description, quantity, price) VALUES ('".$vendor."', '".$description."', '".$quantity."', '".$price."')"; 
$result1=mysql_query($sql1); 

mysql_close(); 
?>


If anybody can suggest where I need to go with that, that would be great.  Like I said above, I've tried about everything I could find any reason to from forum threads I had found in google searches and whatnot.  Also, if there is a good article, link or tutorial that would address this that anybody knows about that would be great.  However, I'm not looking for a link to a product or plugin that will do this stuff for me.  I'm trying to get halfway decent at php and would like to have working code for myself to build upon, modify, and learn from.  Any help is greatly appreciated!!!!

Hey. Third question today. Very stuck on this one. I am displaying a ton of while loops to display a bunch of data from two different tables. there is NO possible way i can combine the two tables. I mean, I can, but I'm not going to because they are two totally different thins. Anyway. Here is what I'm trying to do:
Lets say I have 3 items, a grape, an orange and an apple.
- 3 apples
- 2 oranges
- 1 grape

I'm displaying an update price box for each different fruit. (so 3 different boxes), and one submit button.

I update it, and it does update the price but it only updates the very first row. I want to be able to update every row I types the price in for. Here is my code: (it is quite long):

To help you find it, I'm asking about the "stock" $_GET part, about three quarters down. Thanks in advance for anybody who can help me, I've been stuck on this script all day! Thanks again!

Hi,

I'm using a table to list results from a MySQL query.

I wanted to make the rows of the table alternate colours and found the following code on this website which does the job perfectly:

$counter++;
$bgcolor = ($counter % 2)?"#e8edff":"#ffffff";

echo "<tr class='border'>\n
<td bgcolor='".$bgcolor."'>$n</td>\n
<td bgcolor='".$bgcolor."'>$player</td>\n
<td bgcolor='".$bgcolor."'>$score</td>\n
</tr>\n";

On my webpage i have six tables listing results from six MySQL queries and i use the above code after each query to construct the table and alternately colour the rows blue then white.

My problem arises when there are an odd number of rows in the first table.  This results in the first row of the second table being coloured white, not blue.

I would like the first row of each table to be blue.

Is there a simple way to reset the counter for each table?  Any advice much appreciated.

Thanks.

hi

i have table in my database holding food items.

i need users to be able to order those items individually for example...if apples are third from the top..they should be able to move them up or down the list 1 place at a time perhaps with an up and down arrow.

i have a field in my table called item_order

the only problem is...users are going to be able to insert new items to the database...but i dont know how they can populate the order field...i cant set it to auto increment because the item_id is the primary key auto incrementing...how can i populate the order field?

and then once i have this problem sorted how do i then allow users to change this order?

im looking for code if possible please because ive spent WAY to long on this now and im struggling to grasp things people advise me to do. terminology and methods of accomplishing this are just going over my head.

please help.

Hi all,
I have a data base with the following table:

---member_data---
id ^ mid ^fieldname^ fieldvalue
1 - 2 - applicant - Seth Smith
2 - 4 - firstname - Chris
3 - 4 - lastname - Cooper
4 - 7 - full_name - Joey Jones
5 - 7 - occupation - Programmer
6 - 7 - phone - 800-555-1212


And below is a snippet that I use to display the selected members data for editing

-------------------------------
<table>
<tr>
<td>Name:</td>
<td>Value:</td>
</tr>
<?php

$query = "SELECT * FROM member_data WHERE mid='$mid'";
$result= mysql_query($query);
  while($row = mysql_fetch_array($result)) {

      $fieldname = $row["fieldname"];
      $fieldvalue = $row["fieldvalue"];

?>
<tr>
<td><input type="text" name="<?php echo $fieldname;?>" value="<?php echo $fieldname;?>"></td>
<td><input type="text" name="<?php echo $fieldvalue;?>" value="<?php echo $fieldvalue;?>"></td>
<?php } ?>
</tr>
</table>
-------------------------------

My question is:

- using the Db example above:
- lets say Ive selected mid#7 (member id 7) to edit which is displayed using the snippet code from above.
- once displayed how do I edit  mid#7  given the fact that  mid#7  is located on 3 seperate rows from the same table?

Thank you,
Dave


*ALSO - I tried the snippet below which did Not work.

foreach($_POST as $key => $val) {
$sql = "UPDATE member_data SET fieldname='$key', fieldvalue='$val' WHERE mid='$mid'";
$result = mysql_query($sql);
}

Hi,

I have a problem regarding counting rows in a mysql table. Here is the code:

Code: [Select]
<?php
require_once('includes/connection.inc.php');
$conn = dbConnect('read');
$check = 'SELECT COUNT(*) FROM images';
$checkRes = $conn->query($check) or die(mysqli_error());
if($checkRes <= 0) { header('Location: empty_blog.php'); // redirect to another page
} else { // do something else... }
?>

The error I'm getting: "Notice: Object of class mysqli_result could not be converted to int in C:\xampp\htdocs\photoblog\index.php on line 6"

Any help is greatly appreciated!

Hi all,

So I'm not completely sure on how to do this, but basically this i what i want.

I want the users to be able to create "fields" in my table, so let's say we have a structure like this:

Field 1   Field 2   Field 3
Data 1   Data 2   Data 3

Problem is, that i want my users to update both the <td> and <tr> information via mysql, without altering the database.
And I'm not sure on how I can make sure, that everything gets out in the right order.

I have this so far:

Code: [Select]
<table id="sort-table">
<thead>
<tr>
<?PHP
echo ' <td> Identifier </td> ';

$result = mysql_query("SELECT * FROM fields ORDER BY `order`");
while($row = mysql_fetch_array($result))


{

echo ' <td> ' . $row["name"] . ' </td> ';
}
?>
<th style="width:128px">Options</th>

</tr>
</thead>
This will display the field 1, 2, 3 etc..

My problem is.. How do i get the content displayed in the right order to the right fields.. :/

I hope you understand me, if not, please tell me so I can elaborate ^_^
I know this might seems like a noob question, and I'm sorry that I couldn't search, but I didn't know what to search for.

Hi, I'm trying to build a 'simple' page to improve a process where I work.   I'm wanting to do this.   Read either the last line, the last 10 lines, or something I decide on from a log and display the output in table rows and columns.    I've done this before with loops and db query's, but don't know how to approach it using php only as this is the first time I'm using it.   So right now I have this in a table but it will only display one row.   <tr><td colspan="5">

<?php
$servername = "xxx";
$username = "xxxx";
$password = "xxxx";
	
$dbname = "web216-admin-6d5";

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}

$class_id = $_POST['class_id'];  // This value is from a dropdown
$checkbox = $_POST['checkbox'];	// This is a checkbox next to each record
$user_id = $_POST['user_id']; // this is a hidden value output from the database (in a textbox)

if(isset($_POST['submit']))

{  
for($i=0;$i<count($checkbox);$i++){

$query="INSERT INTO Class_List(user_id,class_id)VALUES('".$user_id[$i]."','".$class_id."')";
 if (mysqli_query($conn, $query)) {
     
       echo "The selected records have been added successfully !";
       echo "<meta http-equiv=\"refresh\" content=\"2;url=search_courses.php\"/>";

     } else {
        echo "Error: " . $sql . ":-" . mysqli_error($conn);
     }
     mysqli_close($conn);
}
?>

Hi,

I am trying to figure out how to insert the following values into another table if they  have a checked box:

$class_id = $_POST['class_id'];  // This value is from a dropdown on the top of the page
$checkbox = $_POST['checkbox'];    // This is a checkbox next to each row
$user_id = $_POST['user_id']; // this is a hidden value output from the database (in a textbox) in each row

basically, each row in the table has a checkbox

If the checkbox is checked then it should insert the user_id field from the checked rows and the value from a drop down (class_id) at the top of a page into another table.

I have managed the code up to here but I need a tutorial or guidance to do the rest.

At the moment I am getting error HTTP 500

I understand that the code is subject to sql injection, but will sort that out later

ok, I'm not sure I know how to ask this question, but I've created a table that allows the user to add rows. The problem is, upon submit only the last row creates variables. How can I make sure every cell in every row sets a different variable?

This is going to be a purchase order system.

Here is my code:
Code: [Select]
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Insert Table Row using DOM</title>
<script language="javascript">
function addRow()
{
var tbody = document.getElementById("po_table").getElementsByTagName("tbody")[0];
var row = document.createElement("TR");
var cell1 = document.createElement("TD");
var cell2 = document.createElement("TD");
var cell3 = document.createElement("TD");
var inp1 =  document.createElement("INPUT");
inp1.setAttribute("type","text");
inp1.setAttribute("name","quantity");
cell1.appendChild(inp1);
var inp2 =  document.createElement("INPUT");
inp2.setAttribute("type","text");
inp2.setAttribute("name","description");
cell2.appendChild(inp2);
var inp3 =  document.createElement("INPUT");
inp3.setAttribute("type","text");
inp3.setAttribute("name","unit_cost");
cell3.appendChild(inp3);
row.appendChild(cell1);
row.appendChild(cell2);
row.appendChild(cell3);
tbody.appendChild(row);
//alert(row.innerHTML);
}
</script>
</head>
<body>
<form method="post" action="review_po.php">
<table id="po_table" border="1">
<tbody>
<tr>
<th bgcolor="#c1c1c1">Quantity</th>
<th bgcolor="#c1c1c1">Description</th>
<th bgcolor="#c1c1c1">Unit Cost</th>
</tr>
<tr>
<td><input type=text name="quantity"></td>
<td><input type=text name="description"></td>
<td><input type=text name="unit_cost"></td>

</tr>
</tbody>
<tfoot>
<tr>
<th bgcolor="#e0e0e0">1</th>
<th bgcolor="#e0e0e0">Shipping</th>

<tr>
<th bgcolor="#e0e0e0">1</th>
<th bgcolor="#e0e0e0">Tax</th>
<td><input type=text name="tax"></td>

</tr>
</tfoot>
</table>
<input type="button" value="Insert Row" onClick="addRow();">
<input type="submit" value="Review" name="review_po">
</form>


</body>
</html> 
right now it goes to this page:

Code: [Select]
<?php

//convert to variables
$quantity = $_POST['quantity'];
$description = $_POST['description'];
$unit_cost = $_POST['unit_cost'];
$extended_cost = $_POST['extended_cost'];
$shipping = $_POST['shipping'];
$tax = $_POST['tax'];

?>

<?php echo $quantity; ?><br>
<?php echo $description; ?><br>
<?php echo $unit_cost; ?><br>
<?php echo $extended_cost; ?><br>
<?php echo $shipping; ?><br>
<?php echo $tax; ?><br>
