Old issue of mine that I'm coming back to. My question is I'm trying to figure out how to work with the select box of options and apply button so that if delete is chosen and the user clicks on apply it performs the deletedivision inside the process page I know it deals with jquery's ajax however this part of it does not that I'm trying to get fixed because as of right now I have if (isset($_POST['deletedivision'])) and I know that's not right and I know I can't apply a name to the option tag because name isn't one of option's allowable attributes.

mods/divisions.php
Code: [Select]
<form action="" method="post">
<label for="actionSelect">With selected items: </label>
<select class="select" name="actionSelect" id="actionSelect">
<option id="1">Edit</option>
<option id="2">Delete</option>
</select>
<button class="button small-button"><strong>Apply</strong></button>
</form>


<?php 
        while ( $row = mysqli_fetch_array ( $result, MYSQL_ASSOC ) ) {
              echo '
              <tr>
              <td><input type=checkbox class=checkbox name=checkbox[] id=checkbox[] value="' . $row['id'] . '" /></td>
  <td>' . $row['divisionname'] . '</td>
  <td>' . $row['name'] . '</td>
  <td class=last>' . $row['datecreated'] . '</td>
  </tr>';
            }
        ?>


processes/divisions.php

if (isset($_POST['deletedivision'])) {
    $checkbox = $_POST['checkbox'];
    $countCheck = count($_POST['checkbox']);
    
    for($i=0;$i<$countCheck;$i++) {
   $del_id  = $checkbox[$i];
       $query = "DELETE from `divisions` where id = $del_id";
       
       mysqli_query($dbc,$query);
    }

}

Hi, I'm new to the forum so this could go in the MySQL section but I'm not sure.

I am trying to make a page that will list all records from a column in HTML table and have a delete button to remove a specific record. I have got to the part where I have listed the records in a table.
Note: Only records from a specific column ('links') are printed.

Here is the code:
Code: [Select]
$con = mysql_connect("localhost","***","***");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("***", $con);

$result = mysql_query("SELECT * FROM main");

echo "<table border='1'>
<tr>
<th>Current links</th>
</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td>" . $row['links'] . "</td>";
  echo "</tr>";
  }
echo "</table>";

mysql_close($con);
How would I go about adding a delete button next to each record to delete that specific record?

Thanks for any help.

Hello,

I want to add text to a file, getting it printed out in index.php and later want to edit/delete per row. I give codes page wise. first the form to take data:
add.php:
Code: [Select]
<?php
?>
<form method="post" action="add_data.php">
<fieldset>
<legend>Student List</legend>
Name : <input type="text" name="uname" /><br>
Content : <input type="text" name="age" />
<br>
<input type="submit" name="submit" value="send" />
</fieldset>
</form>
Next adding text to a file: add_data.php:
Code: [Select]
<?php
$id = 1;
if (file_exists("data.txt"))
{
$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);
foreach ($str_arr as $rec)
{
if ($rec)
{
$id++;
}
}
}

$mode = (file_exists("data.txt"))? "a" : "w";

$fp = fopen("data.txt", $mode);
$line = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|";
$res = fwrite($fp, $line);
fclose($fp);

header("location:index.php");


?>In the index.php, I'd like to fetch data and edit them per row:
Code: [Select]
<?php
$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);
echo "<table border='1'>";
echo "<tr><td>ID</td><td>Name</td><td>Age</td><td>Option</td></tr>";

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
echo "<tr>";
foreach ($rec_arr as $col)
{
echo "<td>$col</td>";
}
print "<td><a href=\"edit.php?id=$id\">Edit</a>/<a href=\"delete.php?id=$id\">Delete</a></td></tr>";
}
}
echo "</table>";

echo "<a href=\"add.php\">Add Data</a>";

?>


Next I want to Edit per row: edit.php:
Code: [Select]
<?php

$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];
if ($id == $_REQUEST["id"])
{
echo "<form action='edit_data.php' method='post'>";
echo "Name :<input type='text' name='uname' value='$name' /><br>";
echo "Age: <input type='text' name='age' value=$age /><br>";
echo "<input type='hidden' name='uid' value=$id />";
echo "<input type='submit' value='Edit'>";
echo "</form>";
}
}
}


?>
From edit.php to edit_data.php where I practically try to edit per row:
Code: [Select]
<?php

$fp = fopen("data.txt", 'r');
$str = fread($fp, filesize("data.txt"));
$str_arr = explode("|", $str);

foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];

if ($id == $_POST['uid'])
{
$new_str = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|";
}
else 
{
$new_str = $id . "--" . $name . "--" . $age . "|"; 
}
}
}

fclose($fp);

$fp = fopen("data.txt", 'w');
fwrite($fp, $new_str);
fclose($fp);


?>
The mechanism is simple. Taking datas from a form, explode them to an array and get them into col/row pattern to edit and delete them. But my problem is when I want to edit in index.php page, specially in this part:
Code: [Select]
print "<td><a href=\"edit.php?id=$id\">Edit</a>
It says, undefined index. But I try to catch this $id in the edit.php page, in this manner, as you see in my code:
Code: [Select]
foreach ($str_arr as $rec)
{
if ($rec)
{
$rec_arr = explode("--", $rec);
$id = $rec_arr[0];
$name = $rec_arr[1];
$age = $rec_arr[2];
if ($id == $_REQUEST["id"])
{
echo "<form action='edit_data.php' method='post'>";
echo "Name :<input type='text' name='uname' value='$name' /><br>";
echo "Age: <input type='text' name='age' value=$age /><br>";
echo "<input type='hidden' name='uid' value=$id />";
echo "<input type='submit' value='Edit'>";
echo "</form>";
}
}
}
Have I done any mistake here? If anyone points out, I'll be obliged.

Not sure how to go about making it so that I can delete and edit a post..

So I am stumped on how to make it to delete and edit post. The key factor for getting the information is the id field. And I am able to get it and display it, but how can I get it to work between all my functions?

This is what I have so far.


<?php
include 'test.php';
function connection()
{

$connection = @mysql_connect('localhost','root','') or die('could not connect to mysql');

$select_db = @mysql_select_db('tutorials') or die('could not connect to database');
}

function delete_post($id)
{

connection();

$query = "DELETE FROM `posts` WHERE `id` = '$id'";

$result = mysql_query($query);
}

function find_posts()
{

connection();

$query = 'SELECT `posts`.`title`, `posts`.`body`, `posts`.`id`, `users`.`username` FROM `posts`, `users` WHERE `posts`.`user_id` = `users`.`id`';

$result = mysql_query($query);

while ($row = mysql_fetch_array($result))

{

$id = $row['id'];

echo '<b>' . $row['title'] . '</b>'  .'<a href=/practice/model/posts.php?action=delete>[delete]</a> <a href=/practice/model/posts.php?action=edit>[edit]</a>' . '<br/>';

echo $row['body'] . '<br/>';

echo $row['username'] . '<p>';

}

}

function find_post($id)
{

connection();

$query = "SELECT `posts`.`title`, `posts`.`body`, `posts`.`id`, `users`.`username` FROM `posts`, `users` WHERE `posts`.`user_id` = `users`.`id` AND `posts`.`id` = '$id'";

$result = mysql_query($query);

$row = mysql_fetch_array($result);

echo '<b>' . $row['title'] . '</b>' . '<br/>';

echo $row['body'] . '<br/>';

echo $row['username'] . '<p>';
}

function create_post()
{

connection();

$title = $_POST['title'];

$body = $_POST['body'];

$query = "INSERT INTO `posts` SET `title` = '$title', `body` = '$body', `created_at` = NOW(), `user_id` = 53";

$result = mysql_query($query);

if(!$result)

{

echo mysql_error();

}
}

delete_post(7);
find_posts();

?>



<?php
$action = $_GET['action'];


switch ($action)
{

case 'create':

echo 'created' . '<br/>';

create_post();

break;

case 'delete':

echo 'deleted' . '<br/>';

delete_post($id);

break;
}

?>



<form action="/practice/model/posts.php?action=create" method="POST">

<input type="text" col="40" name="title" /><br/>

<textarea cols="30" rows="5" name="body"> </textarea><br/>

<input type="submit" name="submit" />
</form>


So yea, I am not sure how to get the 'id' parameters linked between everything that needs it. Sorry for the vague description, but its kind of hard to put it into words. If you need a more detailed description please let me know and I will try to. Pretty much want to be able to delete and edit my posts.

Thank you!

Hello!

We our creating an admin page to display a list of all the items within a mysql database, these items are within a table called "item". Each item is categorized, these categories are in a table called "category" each category has an ID. There is then a table called "links" which links the items to their category using ID's.

We want to display each item by their category with an edit and delete button. We have it so all the items display with the two buttons in no specific order however we are not too sure how to make it so they all display via their category.

Here is the code we are currently using:
Code: [Select]
<?php

$itemlist = mysql_query("SELECT item.item_name, item.item_description, item.item_image, item.item_price, item.item_id FROM item ORDER BY item.item_id ASC");

$item_count = 0;

?>

<?php while( $row = mysql_fetch_array($itemlist) ){?>

<?php if(($row['item.item_name'] == 1) && (isset($item_count) && $item_count < 1)) { ?>
<?php
$item_count ++;
} ?>

<li class="title">

<h3><?php echo $row['item_name'];?></h3><br />

<form action="ourworkadmin.php" method="get">

<input type="hidden" name="item_id" value="<?php echo $row['item_id'];?>" />
<input name="edit" value="Edit" type="submit" />
<input name="remove" value="Remove" type="submit" />

</form>

</li>

<?php } ?>

</ul> <!--Close-items_list-->
       
 </div>

Any help would be appreciated! Thank you!!!

I need Delete Duplicate Email Records That Are Attached To One Account But Can Be Found In Multiple Accounts

I have a table, consumer_mgmt.  It collects consumer information from various forms.  These forms are available through different pages that are part of a business package.

A business can offer these signups to gather names and emails from consumers for various types of specials they may offer.  So a consumer my be in the consumer_mgmt table 5, 10, 15 times for that particular business.

But, that consumer may be in the consumer_mgmt table multiple times for a different business.  So multiple times for multiple businesses.

I need to remove duplicates for each business account so the consumer is only the consumer_mgmt only once for each business.

There are approximately 15,000 rows currently in the consumer_mgmt table.   I'm not sure where to begin on the logic.  Since there are multiple business accounts that the emails are attached to, would one have to build a case for each loop?

Hi I'm using this code to insert multiple records. The code executes but nothing is entered into my database. This usually happens when there's a mismatch in data types.   How do I ensure that description goes in as text which in sql is wrapped in single quotes, but also make sure the other variables go in as numeric.

 // an array items to insert
    $array = array( 'theid'   => $theid,
            'descr'      =>   $descr,
            'costperunit'    => $costperunit,
            'quantity'       => $quantity,
'costperlot'       => $costperlot
            );


    // begin the sql statement
    $sql1 = "INSERT INTO  descriptions (jobid, description, costperunit, quantity, costperlot) VALUES ";

    $it = new ArrayIterator( $array );


    // a new caching iterator gives us access to hasNext()
    $cit = new CachingIterator( $it );


    // loop over the array
    foreach ( $cit as $value )
    {
        // add to query
        $sql1 .= "('".$cit->key()."','" .$cit->current()."')";
       

        if( $cit->hasNext() )
        {
            $sql1 .= ",";
        }
    }

I'm sorry to be back so soon, but I'm up against another mystery.  I'm using the code below to enter a bunch of css data from a spreadsheet into a mysql table.  I think the data file is OK.  The array created by the script checks out with print_r.  (There are many more records than shown.  I truncated it to save space.)

The problem is that I get this error regarding my sql statement, not the data or anything else:

Fatal error: Uncaught PDOException: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'check, name, phone, email, entry_fee, print_fee, image_name, description, med...' at line 1 in /Users/studio/Sites/BannerProject/b-as/_test_site/csv_to_array.php:242 Stack trace: #0 /Users/studio/Sites/BannerProject/b-as/_test_site/csv_to_array.php(242): PDO->prepare('INSERT INTO tbl...') #1 {main} thrown in /Users/studio/Sites/BannerProject/b-as/_test_site/csv_to_array.php on line 242

I've typed it in a dozen times to make sure there are no errors and keep getting the same error.

I tried running a test file and gradually increasing the number of placeholders and at some point I always end up getting the same error,  I can delete the most recent addition and it works again.  Then I can add another placeholder exactly as before and it works the second time.  It feels like a ghost in the machine.

Any idea what I am doing wrong?  An I typing something I don't see?

Any solution for this ?

i want a php solution to print category names in table headers , unit names in table rows and course name(s) in table caption.I have tried foreach loop but how to remove duplicate entries as you can see category name 1 and 2 will become two separate headers instead of one and same is the case with Course 1 and 2.
i have googled but could'nt find any solution. i don't want to remove duplicate entries , all i want to display them once in a table as described above.

Hi,

I have a DB with two tables, customers and orders. One customer may have many orders, What I want to do is do a select on the two tables and get the customer info once, and then all the orders associated with the account.

I saw how to do this once before using a join and then having to use a PHP foreach to break it up. I am just not sure of how to put the two together to make it work, or maybe there is an easier way completely.

Any help is appreciated.

Thanks

How do you do this? Thanks in advance.
