Whenever I am clicking on the prdDetails button, an error is there that
"Uncaught TypeError: Cannot read property style of 'null'" whether more() is called or same() is called.
I am currently working on the XAMPP server.
Other than that everything is working fine.
Your calls to more() and same() occur before the elements which they reference in the DOM.
Move the calls to more() and same() to somewhere after the elements MoreDetails and SameProduct.
This is because it document.getElementById('MoreDetails'); does not receive an DOM element and variable MoreDetails is null.
You should call function more() after DOM elemenet with id MoreDetails, but you call it before so you can't get this DOM element.

I have php function which update all records in data table and need it run by click button in html.
My php function look like this:
<?php
try {
$sql = 'SELECT id_data, date_record, value1, value2, value3 FROM data ';
$s = $pdo->prepare($sql);
$s->execute();
} catch (PDOException $e) {
$error = 'Error with select data' . $e->getMessage();
include 'error.html.php';
exit();
}
while ($row = $s->fetch()) {
$dane[] = array(
'id_data' => $row['id_data'],
'date_record' => $row['date_record'],
'value1' => $row['value1'],
'value2' => $row['value2'],
'value3' => $row['value3']
);
}
if (isset($_GET['edytion'])) {
foreach ($data as $data2) {
try {
$sql = 'UPDATE data SET date_record = :date_record, value1 = :value1, value2 = :value2, value3 = :value3 WHERE id_data= :id_data';
$s = $pdo->prepare($sql);
$s->bindValue(':date_record', $_POST['date_record']);
$s->bindValue(':value1', $_POST['value1']);
$s->bindValue(':value2', $_POST['value2']);
$s->bindValue(':value3', $_POST['value3']);
$s->bindValue(':id_data', $_POST['id_data']);
$s->execute();
} catch (PDOException $e) {
$error = 'Edit data error ' . $e->getMessage();
include 'error.html.php';
exit();
}
}
Header("Location: theme3.php");
}
?>
And my form in html where i try run this look:
<div class="table-responsive">
<table class="table table-bordered">
<thead>
<tr>
<th>Date</th>
<th>Value 1</th>
<th>Value 2</th>
<th>Value 3</th>
</tr>
</thead>
<?php if (isset($data)): ?>
<?php foreach ($data as $data1): $a = 0 ?>
<form action="?edytion" method="post" id='ed'>
<tr class="bg-primary">
<input type="hidden" name="id_data" id="id_data" value="<?php echo $data1['id_data']; ?>">
<td><input type="date" name="date_record" id="date_record" value="<?php echo $data1['date_record']; ?>"> </td>
<td><input type="text" name="value1" id="value1" value="<?php echo $data1['value1']; ?>"> </td>
<td><input type="text" name="value2" id="value2" value="<?php echo $data1['value2']; ?>"> </td>
<td><input type="text" name="value3" id="value3" value="<?php echo $data1['value3']; ?>"> </td>
<!-- <input type="hidden" ondblclick="default" id="id_buttona" value="Edit"/> -->
</tr>
</form>
<?php $a++;
endforeach; ?>
<?php endif; ?>
</tbody>
</table>
<input type="submit" id="id_buttona" onclick="document.getElementById('ed').submit();" value="Edit"/>
</div>
Ultimately when i try update data it update only first record in table, rest of them is invariable.
Anybody know what is wrong and have idea how correct it? I will be grateful for help!
You create too many forms with the same id. Surround the table with the <form> and do foreach on <tr> only.
Something like this
<div class="table-responsive">
<form action="?edytion" method="post" id='ed'>
<table class="table table-bordered">
<thead>
<tr>
<th>Date</th>
<th>Value 1</th>
<th>Value 2</th>
<th>Value 3</th>
</tr>
</thead>
<?php if (isset($data)): ?>
<?php $a = 0; foreach ($data as $data1): ?>
<tr class="bg-primary">
<input type="hidden" name="id_data<?php echo $a; ?>" id="id_data" value="<?php echo $data1['id_data']; ?>" />
<td><input type="date" name="date_record<?php echo $a; ?>" value="<?php echo $data1['date_record']; ?>"> </td>
<td><input type="text" name="value1<?php echo $a; ?>" value="<?php echo $data1['value1']; ?>"> </td>
<td><input type="text" name="value2<?php echo $a; ?>" value="<?php echo $data1['value2']; ?>"> </td>
<td><input type="text" name="value3<?php echo $a; ?>" value="<?php echo $data1['value3']; ?>"> </td>
</tr>
<?php $a++;
endforeach; ?>
<?php endif; ?>
</tbody>
</table>
<input name="row_count" value="<?php echo isset($a) ? $a : 0; ?>" type="hidden"/>
</form>
<input type="submit" id="id_buttona" onclick="document.getElementById('ed').submit();" value="Edit"/>
</div>
The way you created each form for each row will not work well because: (1) all your forms have the same javascript id, when you do getElementById only the first form is affected, (2) when you submit that one form the page reloads and all the changes to other rows are lost.
One solution is to make only 1 form and have different name to all fields. Forms fields are sent by name and value so you need different names for all fields and you don't really need ids.
You can add row count somewhere in the form and then change php to something like this:
$row_count = $_POST['row_count'];
for($i = 0; i < $row_count; i++) {
try {
$sql = 'UPDATE data SET
date_record = :date_record,
value1 = :value1,
value2 = :value2,
value3 = :value3
WHERE id_data= :id_data';
$s = $pdo->prepare($sql);
$s->bindValue(':date_record', $_POST['date_record' . $i]);
$s->bindValue(':value1', $_POST['value1' . $i]);
$s->bindValue(':value2', $_POST['value2' . $i]);
$s->bindValue(':value3', $_POST['value3' . $i]);
$s->bindValue(':id_data', $_POST['id_data' . $i]);
$s->execute();
}
catch (PDOException $e) {
$error = 'Edit data error ' . $e->getMessage();
include 'error.html.php';
exit();
}
}

<input type="submit" name="submit" value="Submit Answer" class="btn">
</form>
After hitting the submit button, im only getting s_id, q_id , but the score is still 0 even if I selected the correct answer
My problem here is getting the selected radio button and then comparing it to the answer(where is in the database)
I just did a quick mock up and this worked for me.
$answer = $_POST["'" . $rows['q_question'] . "'"];
if ($correct_answer == $answer)
{
$score++;
}
I have the following php page,
which has a dropdown box and when the value closed is chosen it is meant to open a text box.
I have embdedded the javascript inside php but for some reason it is not working.

For testing purposes:
comment all until your program begin in
/*
*/
$content .="
then change:
$template->SetTag("content", $content);
echo $template->Display();
for:
echo $content;
finally, inside the script tags write:
alert('Javascript is working');
I made it and got the program running. You problem is in the $template class, not in this code.
Cheers,
I'm pulling down two tables from the db. There's a Javascript function that adds a row from Table2 into the Table1. What i've been trying to do is get the data from Table1 on the confirm_trade.php page so I can put it into the db but can't figure out how to pull that row(item_id). I thought putting the table in a form would allow me to access them through the $_POST but that's not working. How to add an identifier to the jquery row so I can grab on the confirm page?
The appended rows coming from the jQuery function are the rows I need the item_id from.
function addto(obj)
{
var $row = $(obj).parents("tr");
var $table = $("#tradee");
var item_id = $row.find(".item-id").text();
var item_name = $row.find(".item-name").text();
var item_desc = $row.find(".item-desc").text();
var newTR = $("<tr><td>"+item_id+"</td><td>"+item_name+
"</td><td>"+item_desc+"</td></tr>");
$table.append(newTR);
}
Table2:
<div id='fixedDiv'>
<form action="confirm.php" method="post">
<table align="center" id="Table2">
<tr><td>Other Item</td></tr>
<?php while($rowi =$item->fetch_assoc())
{?>
<tr>
<td>
<?php echo $rowi['item_id']; ?>
</td>
<td>
<?php echo $rowi['item_name']; ?>
</td>
<td><?php echo $rowi['item_description'];?></td>
</tr>
<?php } ?>
<tr>
<td><input type="submit" name="submit" value="Continue"/></td>
</tr>
</table>
</form>
</div>
<br>
Table 1:
<table align="center" id="Table1">
<tr><th>item_id</th>
<th>Cat_id</th>
<th>Name</th>
<th>Description</th>
</tr>
<?php while($row =$item_results->fetch_assoc())
{?>
<tr></tr>
<tr>
<td class="item-id"> <?php echo $row['item_id']; ?> </td>
<td><?php echo $cat_id = $row['cat_id']; ?> </td>
<td class="item-name"><?php echo $item_id = $row['item_name'];?></td>
<td class="item-desc"><?php echo $item_descrip = $row['item_description'];?>
</td>
<td><input type="button" class="added" onclick="addto(this)"
value="Add" />
<td><input type="button" class="removed" onclick="remove()"
value="Remove" >
</td>
</tr>
<?php } ?>
</table>
Judging by your code, you can use <input type="hidden" name="some_hidden_data" value="field-value">. be sure that you also wrap your table with <form method="post"></form>
the hidden field will be then included as $_POST['hidden_field_name'];
