Good morning,
I was searching, but couldn't find answer :(
I have a table created dynamically with data taken from MSSQL:
$tabelka = '
<form action="index.php" method="post">
<table border =1 width=40% class="hoverTable"><tr>
<td width=10%><B>Biuro</B></td>
<td width=10%><b>Drukarka</b></td>
<td width=20%><b>Toner</b></td>
<td width=10%><b>Na stanie</b></td>
<td width=10%><b>Zamówionych</b></td>
<td width=10%><b>Akcja</b></td></tr>';
$sql = 'select * from raportTonerow';
if ($result = sqlsrv_query($conn, $sql)) {
while ($row = sqlsrv_fetch_array($result)) {
$tabelka .= '
<tr><td width=10%>'.$row['kodBiura'].'</td>
<td width=10%>'.$row['nazwaDrukarki'].'</td>
<td width=20%>'.$row['toner'].'</td>
<td width=10%>
<input type="number" name="naStanie" size=10% maxlength=1 value="'.$row['naStanie'].'"></td>
<td width=10%><input type="number" name="zamowionych" size=10% maxlength=1 value="'.$row['zamowionych'].'"></td>
<td width=10%><input type="submit" value="Aktualizuj" name="akt"></td>';
}
}
$tabelka .= '</form></table>';
and
if (isset($_POST['akt'])) {
echo "test ".$_POST['zamowionych'];
}
it is showing me only last data from table. How can I pass variables from each row?
What I want to have is: when user click on button on the row only data from that row will be send in form.
thank you
Lukasz

I'm creating a table that uses PHP to pull from a MySQL database that I have. I think I've got everything where I want it to be, however the only problem I'm having is that the results seem to be (for lack of a better word) "behind". What I mean by that is that my first page index.php is where I'm accepting user edits to the database. Once they click Update it sends them to my results.php file that is supposed to actually perform the SQL UPDATE and then display the updated table.
It updates the table just fine according to XAMPP's database editor. However, when I said "behind" I mean that the page loads, updates but doesn't display the updated data until either the user refreshes the page or returns to the first page THEN comes back. I'm not sure what could be causing it, so I'm hoping someone here can help me. I feel like the reason is something as simple as I'm just running the code in the wrong order, but I don't know for sure. My code is below:
index.php
<html>
<body>
<?php
include('dbconnect.php');
$query = "SELECT * FROM vw_events";
$result = mysqli_query($conn, $query);
$count = mysqli_num_rows($result);

Also if someone can give me some guidance as to how to run the htmlspecialchars function on my arrays within results.php I'd really appreciate it. I've already tried to create a for loop for literally each array but that didn't work. I've tried using ->
<?php
function htmlspecial_array(&$variable) {
foreach ($variable as &$value) {
if (!is_array($value)) { $value = htmlspecialchars($value); }
else { htmlspecial_array($value); }
}
}
but that also didn't work, and I've tried using the array_walk_recursive but to no avail. I want to try and do something like W3Schools' example here W3Schools Form Validation towards the bottom of the page where it says Validate Form Data With PHP and then gives an example.
The result you get from the UPDATE query is the number of affected rows in your database. To correctly display the updated data, you need to re-fetch from the database before you generate the HTML. You should rearrange your code in results.php like this:
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
error_reporting(E_ALL);
ini_set('display_errors',1);
require_once('dbconnect.php');
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
$id = $_POST['event_id'];
$title2 = $_POST['title'];
$date2 = $_POST['date'];
$speaker2 = $_POST['speaker'];
$building2 = $_POST['building'];
$room2 = $_POST['room'];
$query = "SELECT * FROM vw_events";
$result = mysqli_query($conn, $query);
$count = mysqli_num_rows($result);
for($i=0;$i<$count;$i++) {
$sql="UPDATE events SET title='$title2[$i]', event_date='$date2[$i]', speaker='$speaker2[$i]', building='$building2[$i]', room='$room2[$i]' WHERE event_id='$id[$i]'";
$result1=mysqli_query($conn, $sql);
}
}
$query = "SELECT * FROM vw_events";
$result = mysqli_query($conn, $query);
Side note: If your data is sensitive, you may want to read about mysqli prepared statement so hackers cannot tamper with your queries.
Regarding your question about htmlspecialchars, see Stackoverflow "Execute htmlspecialchars on a multi level array".
I have a table called "project_name" in my database called "encrypt_decrypt". The table contains only 1 column called "name" which contains different values of name (ex : p1, p2, p3...). I have to retrieve this values(p1,p2,p3..) from my database and display it on a registration form with each value displaying one below the other having a checkbox with it so that user can select any of the name while registering! How do i do this in php ???
Thanks in advance!
<html>
<body>
<form name="reg" action="code_exec2.php" onsubmit="return validateForm()" method="post">
<table width="274" border="0" align="center" cellpadding="2" cellspacing="0">
<tr>
<td><div align="right" style="white-space:nowrap" >Please select the project:</td>
</tr>
<tr>
<td><div align="right"><input type="checkbox" name="project[]" ></div></td>
<td><?php
session_start();
include('connection2.php');
$row=mysql_query("select * from project_name");
$array= array();
$output = mysql_fetch_assoc($row);
while($output){
$array[] = $output;
}
print_r($array);
?></td>
</tr>
<tr>
<td><div align="right"><input type="checkbox" name="Select all"
value="select all" onclick="toggle(this)"></div></td>
<td>Select all</td>
</tr>
<tr>
<td><div align="right"></div></td>
<td><input name="submit" type="submit" value="Submit" /></td>
</tr>
</table>
</form>
</body>
Try this.
$result=mysql_query("select * from project_name");
$checkboxes=array();
while($r=mysql_fetch_assoc($result)){
$checkboxes[]='<input type="checkbox" name="names[]" value="'.$r['name'].'">'.$r['name'].'<br />';
}
Then echo below wherever you want the checkboxes to appear.
echo implode("\n",$checkboxes);
Assuming, that your connection to db is correct, you need to change the way you display results:
<?php
session_start();
include('connection2.php');
$row=mysql_query("select * from project_name");
$array= array();
while($output = mysql_fetch_assoc($row)){
//now you have row with name, and you need to display each name with new tr:
?>
<tr>
<td><div align="right"><input type="checkbox" name="project[]" value="<?php echo $output['name'] ?>"></div></td>
<td><?php echo $output['name'] ?></td>
</tr>
<?php } // closing while loop
?>
Note that I added value to checkbox - if you want to do something with checked project, you have to know which one it was.
And remember taht mysql_ functions are depreated! You should use PDO or mysqli_ instead
i tried this and i got: any ways thanks for all your help :)
<?php
include('connection.php');
$r=mysql_query("select distinct name from project_name");
$ProdArray=array();
while ($row = mysql_fetch_object($r)) {
array_push($ProdArray,$row->name);
}
foreach($ProdArray as $p) {
echo "<tr>";
echo "<td><div align='right'>";
echo "<input type='checkbox' name='project[]' value=" .$p. " />";
echo "</div></td>";
echo "<td>$p</td>";
echo "</tr>";
}
?>
I figured out how to update a table with multiple columns using checkboxes, except when more than one checkbox is selected the update will only happen for one of the columns not both. Could someone please help? Thank you!
Here is the working code for the table:
<table width="100%" border="0" cellspacing="1" cellpadding="0">
<tr>
<td><form name="frmactive" method="GET" action="assigncases1.php">
<table width="100%" border="0" cellpadding="3" cellspacing="1">
<tr>
<select name="assigned_to">
<option value=""></option>
<option value="Kristin Dodd"> Kristin Dodd </option>
<option value="Matt Ursetto"> Matt Ursetto </option>
<option value="Derek Bird"> Derek Bird </option>
<option value="John Castle"> John Castle </option>
<option value="Martin Delgado"> Martin Delgado </option>
</select>
<br>
<input type='submit' value = 'Assign'>
</tr>
<tr>
<td> </td>
<td colspan="4" align="center"><strong>Update multiple rows in mysql with checkbox<br>
</strong></td>
</tr><tr>
<td align="center" bgcolor="#FFFFFF"></td>
<td align="left"><strong>Name</strong></td>
<td align="left"><strong>SSO</strong></td>
<td align="left"><strong>case_status</strong></td>
<td align="left"><strong>Assigned To:</strong></td>
</tr>
<?php
$result=mysql_query($sql);
$count=mysql_num_rows($result);
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td align="center"><input name="checkbox" type="checkbox" id="checkbox[]" value="<?
echo $rows['id']; ?>"></td>
<td><? echo $rows['full_name']; ?></td>
<td><? echo $rows['sso']; ?></td>
<td><? echo $rows['case_status']; ?></td>
<td><? echo $rows['assigned_to']; ?></td>
</tr>
<?php
}
?>
<tr>
<td colspan="5" align="center"> </td>
</tr>
</table>
</form>
</td>
</tr>
</table>
And this is what I have for the php page that take the info.
// Retrieve data from database
$checkbox = $_GET['checkbox'];
$assigned_to = $_GET['assigned_to'];
// update data in mysql database
$sql="UPDATE rmstable2 SET assigned_to='$assigned_to' WHERE id='$checkbox'";
$result = mysql_query($sql);
$count = mysql_numrows($result);
{
mysql_query("UPDATE `rmstable2` SET `assigned_to` = '$assigned_to'
WHERE `id` = '$checkbox'")
or die(mysql_error());
}
//If they did not enter a search term we give them an error
if ($assigned_to == "")
{
echo "<h3>You forgot to enter a required field. Please try again.</h3><br>";
}
// if successfully updated.
else if($assigned_to !== "")
{
echo "<b>Update Successful</b><br>";
echo "<br>This case was assigned to:<b> $assigned_to</b><br>";
echo "<br>To see the change go back and click on <b>Refresh Page</b> if you assigned it
to someone other than you, the case will disappear and show up in their list of
assigned cases.";
}
else {
echo "ERROR";
}
?>
In your HTML, you're defining your checkboxes with the name checkbox - so only one value will be sent to PHP. To get an array of values, update the checkboxes to be created with name="checkbox[]" and when the form is submitted, you can use the selected values like an array.
In that case, you'll be able to loop through each item with:
$checkbox = $_GET['checkbox'];
$assigned_to = $_GET['assigned_to'];
foreach ($checkbox as $id) {
// do a very basic validation to see if the ID is numeric
if (!is_numeric($id)) continue;
$sql = 'UPDATE rmstable2 SET assigned_to="' . mysql_real_escape_string($assigned_to) . '" WHERE id=' . (int)$id;
mysql_query($sql);
}
Also, as always worth noting, the mysql_* functions are being deprecated and you should consider to start using either mysqli_* or PDO methods.
It's been a while since I looked at php and I've got a brain block. I'm trying to get the values from a table using foreach so that I can store the values in a session and also display the number of items that have been ordered.
eg 2 of item number 4 etc
here's the table / form
<form id="products" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<?php
//every item from the products table is queried because all fields need to be displayed
$sSQL = "SELECT * FROM products";
$rsResult = mysql_query($sSQL);
?>
<table id="products_table">
<tr style="font-weight:bold">
<td style="text-align:center">ID</td>
<td>Ref No.</td>
<td>Product Name</td>
<td>Description</td>
<td style="text-align:right">Price</td>
<td colspan='2' style='text-align:center'>Add To Order</td>
</tr>
<!--for each record in the table that matches the query a row is created in the table and the data in the relevant field is displayed-->
<?php while ($row = mysql_fetch_array($rsResult)){ ?>
<tr>
<input type="hidden" name="productID[<? echo $row['productID']; ?>]" value="<? echo $row['productID']; ?>" />
<td style="text-align:center"><? echo $row['productID']; ?></td>
<td><? echo $row['productReference']; ?></td>
<td><? echo $row['productName']; ?></td>
<td><? echo $row['productDescription']; ?></td>
<td style="text-align:right"><? echo '£'. $row['productPrice']; ?></td>
<td style="text-align:center"><span>Qty</span><input type='text' name="qty[<? echo ($_POST['qty']); ?>]" value="" ></td>
<? } ?>
</table>
Heres the php
<?php
foreach($_POST as $key => $value){
echo $key . ' ' .$value.'<br />';
print_r($key);
}
?>
I know that the php is no where complete for filling sessions etc, I just can't work out how to get the values out of the form. This php was my attempt to try and at least get some kind of value out of it
Any help is greatly appreciated
in your code , there is no need of
<input type="hidden" name="productID[<? echo $row['productID']; ?>
field .
also change the line
<td style="text-align:center"><span>Qty</span><input type='text' name="qty[<? echo ($_POST['qty']); ?>]" value="" ></td>
to
<td style="text-align:center"><span>Qty</span><input type='text' name="qty[<? echo ($row['productID']); ?>]" value="" ></td>
so that after the submission of the form , you can access the posted values with :
$sSQL = "SELECT * FROM products";
$rsResult = mysql_query($sSQL);
while ($row = mysql_fetch_array($rsResult))
{
echo $_POST['qty'.$row['productID']];
}
why don't you just display data in inputs with proper names?
hey guys im having trouble with an array. all i need is for the query to update 2 columns on the table based on the records id
The table has a column called OffID and it looks for any record that has not yet been authorised. to mark it authorised the user will select a check box for either authorise or deny and then press the submit button. however at the moment i have 9 records which show in the table each with there own unique id but when submit is selected it will only update one. any help in showing where ive gone wrong would be grateful and cheers in advance :)
ok i edited the code but it is only now setting the first record. so if there are 8 records and i choose accept for the first record and deny for the second record both the accept and deny are set to the first record in the database my new code is below
<?php
$path = $_SERVER['DOCUMENT_ROOT'];
$path .= "/Apollo/dbc.php";
include_once($path);
$rs_results = mysql_query("SELECT * FROM off WHERE IsItAuthorised='0' and isitsick='0' ORDER BY DayOff");

isn't it because your $id etc isn't passes an array:
$id = $_POST['id'];
$approve = $_POST['approve'];
$deny = $_POST['deny'];
You're using $_POST['id'] but nowhere in your <form/> do I see any <input name="id[]"/> which could provide the data
