i want insert post text box values of each selected check boxes to the database.
<input type="checkbox" name="email[]" value="<?php echo $actions_to_be[$z]['student_email'] ?>" />
<input type="text" name="timetable_id[]" value="<?php echo $actions_to_be[$z]['timetable_id'] ?>" size="10px"/>
<input type="text" name="sid[]" value="<?php echo $actions_to_be[$z]['sid'] ?>" size="10px" />
<input type="checkbox" name="email[]" value="<?php echo $i; ?>" />
<input type="text" name="timetable_id[<?php echo $i; ?>]" value="<?php echo $actions_to_be[$z]['timetable_id'] ?>" size="10px"/>
<input type="text" name="sid[<?php echo $i; ?>]" value="<?php echo $actions_to_be[$z]['sid'] ?>" size="10px" />
$i should be increased for every box of course. Then you can simply take the ids from the $_POST['email'] array (possibly rename it to something more meaningful though) and retrieve the values in $_POST['timetable_id'][$id] and $_POST['sid'][$id].

since I need to update per data, how do you create one button to update all data for the table?
document.querySelector('form').addEventListener('submit', (e) => {
const formData = new FormData(e.target);
// Now you can use formData.get('foo'), for example.
// Don't forget e.preventDefault() if you want to stop normal form .submission
});
This is a nitpicky answer, but let me explain why this is a better solution:
We're properly handling a form submit rather than a button press. Some people like to push enter on fields. Some people use alternative input devices such as speech input or other accessibility devices. Handle the form submit and you correctly solve it for everyone.
We're digging into the form data for the actual form that was submitted. If you change your form selector later, you don't have to change the selectors for all the fields. Furthermore, you might have several forms with the same input names. No need to disambiguate with excessive IDs and what not, just track the inputs based on the form that was submitted. This also enables you to use a single event handler for multiple forms if that is appropriate for your situation.
The FormData interface is fairly new, but is well supported by browsers. It's a great way to build that data collection to get the real values of what's in the form. Without it, you're going to have to loop through all the elements (such as with form.elements) and figure out what's checked, what isn't, what the values are, etc. Totally possible if you need old browser support, but the FormData interface is simpler.
I'm using ES6 here... not a requirement by any means, so change it back to be ES5 compatible if you need old browser support.
i want to get the textfield value and assign it for the radio button value
my code is working but not from the first time
after the first submit it will work perfectly
how do i make it work from the first page load
here is my code
<input type="text" name="optionAtxt" value="<?php echo #$_POST['optionAtxt'] ?>" /> <input type="radio" name="option" required value="<?php echo #$_POST['optionAtxt'] ?>">
<input type="text" name="optionBtxt" value="<?php echo #$_POST['optionBtxt'] ?>" /> <input type="radio" name="option" value="<?php echo #$_POST['optionBtxt'] ?>">
<input type="text" name="optionCtxt" value="<?php echo #$_POST['optionCtxt'] ?>"/> <input type="radio" name="option" value="<?php echo #$_POST['optionCtxt'] ?>">
<input type="submit" name="submit" value="Add" />
<input type="hidden" name="submitted" value="1" />
<?php
if (isset($_POST['submitted'])) {
$selected = trim($_POST['option']);
echo $selected;
}?>
How would I display student.Student instead of student_id
<?php
for ($i = 0; $i < $chkcount; $i++) {
$id = $chk[$i];
$res = $MySQLiconn->query("SELECT Student.ID, student.Student, student.School,student.PR, Jumps.dis_ft_1, Jumps.dis_in_1, Jumps.dis_ft_2, Jumps.dis_in_2, Jumps.dis_ft_3, Jumps.dis_in_3, Jumps.dis_ft_4, Jumps.dis_in_4, Jumps.dis_ft_5, Jumps.dis_in_5, Jumps.dis_ft_6, Jumps.dis_in_6
FROM Student LEFT JOIN Jumps ON Student.ID = Jumps.student_id WHERE ID=" . $id);
while ($row = $res->fetch_array()) {
?>
<tr>
<td>
<input type="hidden" name="id[]" value="<?php echo $row['ID']; ?>"/>
Student ID: <input type="text" name="st[]" value="<?php echo $row['student_id']; ?>"
class="form-control"/>
Attempt 1 <input type="text" name="df1[]" value="<?php echo $row['dis_ft_1']; ?>"
class="form-control"/>

Not sure it can be done. But Student name would be better than student id.
Wouldn't post with more text so just typing so it will post.
I am learning PHP.
If there is only one field called Student i.e Student.Student, then you could just output the name <?php echo $row['Student']; ?>.
However, if there are ever name clashes, you can always give the field a new name for PHP to access.
SELECT Student.ID, Student.Student AS some_new_name FROM ....
<?php echo $row['some_new_name']; ?>
I have a big form that contains X amount of posts that has 15 fields per post along with 1 hidden field.
Let's assume I have 14 posts. This means my form would send 211 fields (14x15 fields plus 1 hidden field).
The user does not have to fill in all fields.
I want to count the number of posts that the form sends but I seem to be running into difficulty.
Using count($_POST) returns 152. This leads me to believe that count() is ignoring empty fields.
As a result, using a formula such as (count($_POST) - 1) / 15 would return the wrong result (10.0666) and is inefficient should the number of fields change in the future.
So, does anyone have any ideas as to how to get the proper count of my posts?
My form looks like so:
<form name="scraped" action="<?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>" method="post">
<input type="hidden" name="OSscraper_hidden" value="N">
<?php
$inpCnt = 0;
foreach($articles as $item) {
?>
<input type="text" name="title_<?php echo $inpCnt; ?>">
<input type="text" name="name_<?php echo $inpCnt; ?>">
<input type="text" name="url_<?php echo $inpCnt; ?>">
<input type="text" name="img_<?php echo $inpCnt; ?>">
<input type="text" name="pet_<?php echo $inpCnt; ?>">
<input type="text" name="color_<?php echo $inpCnt; ?>">
<input type="text" name="value_<?php echo $inpCnt; ?>">
<input type="text" name="height_<?php echo $inpCnt; ?>">
<input type="text" name="weight_<?php echo $inpCnt; ?>">
<input type="text" name="hair_<?php echo $inpCnt; ?>">
<input type="text" name="eyes_<?php echo $inpCnt; ?>">
<input type="text" name="race_<?php echo $inpCnt; ?>">
<input type="text" name="phone_<?php echo $inpCnt; ?>">
<input type="text" name="address_<?php echo $inpCnt; ?>">
<input type="text" name="zip_<?php echo $inpCnt; ?>">
<?php
$inpCnt++;
} ?>
<input type="submit" value="Submit">
</form>
Change your form to look like:
<input type="text" name="foo[<?php echo $inpCnt; ?>][title]">
<input type="text" name="foo[<?php echo $inpCnt; ?>][name]">
<input type="text" name="foo[<?php echo $inpCnt; ?>][url]">
Then you will get:
$_POST['foo'] = [
0 => ['title' => '...', 'name' => '...', 'url' => '...'],
1 => ...,
...
];
It saves you from having to do the grouping yourself, and is easier to count or iterate over the input.
why not just count($articles)*15 and echo into a hidden input. You are using another hidden input anyway....
Try this code, and demo is here
Please just use the idea not the exact copy.
<?php
error_reporting(E_ALL ^ E_NOTICE);
//debugging
if(#$_POST['submit'] == 'Submit'){
echo '<pre>';
print_r($_POST);
echo '</pre>';
echo "<br>\n";
echo 'Number of posts = count($_POST["posts"])='.count(#$_POST['posts'])."<br>\n";
//finding number of posts that are set and not empty
$count = 0;
foreach($_POST['posts'] as $v1){
//$v is an array
foreach($v1 as $v1k=> $v1v){
if(strlen($v1v) > 0){
++$count;
$inputs[$v1k] = $v1v;
}
}
}
echo 'Count of non-empty posts = $count = '.$count."<br>\n";
echo '<pre>';
print_r($inputs);
echo '</pre>';
}
?>

I am new to php and mysql. i've used radio buttons to save the type of my account records i can insert the data successfully but when i try to get that data (whether type S is selected or type T is selected) from sql to update it further i cant do that. i dont know how to get the data of radio buttons from my sql.. please help
<form method="post" action="users-edit-action.php">
<input type="hidden" value="<?php echo $accountid; ?>" name="id" />
<label>Email/Username:</label><input type="text" name="email" value="<?php echo $email; ?>" /><br /><br />
<label>Password:</label><input type="password" name="password" value="<?php echo $password;?>" /><br /><br />
<label>First Name:</label><input type="text" name="firstname" value="<?php echo $firstname; ?>" /><br /><br />
<label>Last Name:</label><input type="text" name="lastname" value="<?php echo $lastname; ?>" /><br /><br />
<label>Type:</label><br />
<input type="radio" name="type" value="<?php echo $type; ?>" /> Student<br />
<input type="radio" name="type" value="<?php echo $type; ?>" /> Teacher<br />
<input type="submit" value="Edit" />
</form>
this is how i get the value from database.. im sure iam doing wrong, please help me solve this..
You have to check which type you got from the database and according to that add this attribute to the input element: checked="checked". So the whole selected tag would look like this:
<input name="type" type="radio" checked="checked" value="the one PHP returned" />
And the other input tag would also be there, but without the checked attribute.
You just need to do the PHP check on what element to put the attribute.
The whole part:
<input type="radio" name="type" value="S" <?php if ($type == 'S') echo 'checked="checked"'; ?>" /> Student<br />
<input type="radio" name="type" value="T" <?php if ($type == 'T') echo 'checked="checked"'; ?>" /> Teacher<br />
The value of your radio-buttons is fixed and does not depend on the value in the database, only whether it is checked or not.
It should be something like:
<input type="radio" name="type" value="S" <?php echo ($type == 'S') ? 'checked' : ''; ?> /> Student<br />
<input type="radio" name="type" value="T" <?php echo ($type == 'T') ? 'checked' : ''; ?> /> Teacher<br />
