I have searched all over this website, but not yet found the answer for this. Pr maybe I am not able to apply it correctly. I have a form that grabs all photos with a certain GALLERY_id attached to it. The backend user can then change the title of the photo and change the tags. After submitting the form the query should update all rows. Here is what I have so far which does not doe anyting:
THE FORM
if(isset($_GET['id']))
{
$id=$_GET['id'];
$result = $db->prepare("SELECT * FROM photos WHERE gallery_id = :gallery_id ");
$result->bindParam(':gallery_id', $id);
$result->execute();
echo '<form action="" method="POST">';
echo "<ul id='photos'>";
for ($i = 0; $row = $result->fetch(); $i++)
{
$id = $row['id'];
$title = $row['title'];
$tags = $row['tags'];
$src = $row['src'];
echo "<li><a class='lightbox' href='images/$src'><img src='images/$src' id='$id' alt='$title' /></a><br />";
echo "<input type='text' name='photo_title' value='$title' /><br />";
echo "<input type='text' name='photo_tags' value='$tags' />";
echo "<input type='hidden' name='photo_id' value='$id' />";
echo "</li>";
}
echo "</ul>";
}
?>
<div style="clear:both"></div>
<input type="submit" name="changeTitle" value="Save"/>
</form>
UPDATE QUERY
if (isset($_POST['changeTitle']))
{
foreach ($_POST as $p)
{
$id=$p['photo_id'];
$title=$p['photo_title'];
$tags=$p['photo_tags'];
$sql = "UPDATE photos SET title=?, tags=? WHERE id=?";
$query = $db->prepare($sql);
$query->execute(array($title, $tags, $id));
}
}
Since you have multiple html fields with same names, you have to submit them as an arrays:
echo "<input type='text' name='photo_title[]' value='$title' /><br />";
echo "<input type='text' name='photo_tags[]' value='$tags' />";
echo "<input type='hidden' name='photo_id[]' value='$id' />";
After submitted, loop through any array variable like
foreach ($_POST['photo_id'] as $key => $photo_id) {
$id = $photo_id;
$title = $_POST['photo_title'][$key];
$tags = $_POST['photo_tags'][$key];
$sql = "UPDATE photos SET title=?, tags=? WHERE id=?";
$query = $db->prepare($sql);
$query->execute(array($title, $tags, $id));
}
I am using the following code to display certain rows from my database table:
<?php
$searchtype=$_POST['searchtype'];
$searchterm=$_POST['searchterm'];
$searchterm= trim($searchterm);
if (!$searchtype || !$searchterm)
{
echo 'Error';
exit;
}
if (!get_magic_quotes_gpc())
{
$searchtype = addslashes($searchtype);
$searchterm = addslashes($searchterm);
}
$db = include "connect2db.php";
$query = "select * from notes where ".$searchtype." like '%".$searchterm."%'";
$result = $db->query($query);
$num_results = $result->num_rows;
echo '<p>Number of rows found: '.$num_results.'</p>';
for ($i=0; $i <$num_results; $i++)
{
$row = $result->fetch_assoc();
echo '<i>';
echo stripslashes($row['date']);
echo '</i><br /> ';
echo '<b>';
echo stripslashes($row['notetitle']);
echo '</b><br /> ';
echo stripslashes($row['note']);
echo '<br /><br /> ';
echo '</p>';
}
$result->free();
$db->close();
?>
Now I would like to display an edit-link for each row displayed, that can open a new page in which it is possible to edit a specific row. I already have the code that lets you edit the row:
<?php
if ($_REQUEST['save']=="Save") { // is data submitted?
// create variables
$noteid = $_REQUEST['noteid'];
$coursename = $_REQUEST['coursename'];
$notetitle = $_REQUEST['notetitle'];
$note = $_REQUEST['note'];
$query = "UPDATE notes SET ";
$query .= "coursename='$coursename', ";
$query .= "notetitle='$notetitle', ";
$query .= "note='$note' ";
$query .= "WHERE noteid='$noteid'";
$result = $db->query($query);
} elseif ($_REQUEST['delete']=="Delete") { // is data to be removed?
$noteid = $_REQUEST['noteid'];
$query="DELETE FROM notes WHERE noteid='$noteid'";
$result = $db->query($query);
}
?>
<div class="formular">
<div class="row1">
<p>Id</p>
<p>Notetitle</p>
<p>Note</p>
</div>
<?php
$query = "SELECT * FROM notes ORDER BY noteid DESC";
$result = $db->query($query);
while ($row = mysqli_fetch_array($result)) {
echo "<form ".$_SERVER['PHP_SELF']." name='edit-form' method='post' class='row1'>\n";
echo "<p class='align_top padding_top'>".$row['noteid']."<input type='hidden' name='noteid' value='".$row['noteid']."' /></p>\n";
echo "<p class='align_top'><input type='text' name='notetitle' value='".$row['notetitle']."' /></p>\n";
echo "<p><textarea name='note' rows='10' cols='50'>".$row['note']."</textarea></p>\n";
echo "<p><input type='submit' name='save' value='Save' /></p>";
echo "<p><input type='submit' name='delete' value='Delete' /></p>";
echo "</form>\n";
}
echo '</div>';
$result->free();
$db->close();
?>
What I am struggling with is how to display an edit-link for each row that lets you open a page where you can edit/delete the content of only that row.
I hope someone can help, I am very new at this.
Thank you!
Add a button next to each row that opens an edit page (or modal) with the id inside, example: <button onclick="edit('randomId')">Edit RandomId </button>
You could implement something different that accepts the unique id of that specific row and open a new page or modal with it.
I'm trying to create a user record to input into a phpmyadmin database.
createUserRecord($usersTable, [$r2,"'".$_POST["firstName"]."'","'".$_POST["lastName"]."'","'".$_POST["username"]."'","'".$_POST["password"]."'","'".$_POST["admin"]."'","'".$_POST["email"]."'"]);
I think there is an issue with the quotation marks or concatenation of the $_POST variables.
There is a record created in the phpmyadmin database, but the values are either not there for the text data types or the two integer value are showing up as 0. When I use print_r to print the values of this createUserRecord, it only prints '1'.
This is the code for the signup page that creates user records:
<html>

How do I refresh the table when I click EDIT NOW Button? or this is easier, how do I make refresh button to refresh the table? I have no knowledge on JSP to auto refresh. However, I manage to make an onchange event so when I choose menu, it will refresh upon changing. When I edit a data and submit, it does not refresh. How do I re-execute the echo of table? Thanks!

I would use 2 pages view.php and edit.php. View would display the data with link to edit. When you click edit it would open edit.php to load the form to edit data and save it to db. Then issue the command
header("Location: view.php");
to reload the view.php and display the new data

It's so easy. If you fetch your table's values after edit or delete operation, sql will bring fresh data.
i am creating a form to do billing and i had a fatal error on the total_amt_array. Also, how do i parse an array of items into database? The form is in the Create Invoice and the invoicesubmit is where it adds all the arrays into the database. Anyone can explain to me why i can't make a total sum of the discount, amount and quantity array.
Also, does anyone have an easier way to calculate all of the total_amt_array. I've searched stackoverflow and others find the final total amount by adding the entire cost column to get the final total cost amount.

First you have:
echo "<td>"?><input type='text' size="50" name='amount[]' value='' /><?php "</td>";
^^---create an array in $_POST
Then:
$amount_array = $_POST['amount'];
^^^^^^^^^^^----this is now an array
Then:
$total_amt_array = ($amount_array - ($amount_array * ($discount_array/ 100))) * $quantity_array ;
This code boils down to:
$total_amt_array = Array - (Array * (Array / 100))) * Array;
You cannot multiply/divide arrays in PHP.
