I want to define dynamic form id for the following example form.
The following code doesn't give me the result I want. for example, instead of <form id="form1">,
I get this result : <form id='form''1'>
How should I write it so it gives me the result I want? Thanks !!
<?php
while ($data = mysqli_fetch_array($subject)) {
echo "<form id='form'.'{$data['productID']}' method='post' action=' ' data-checktable='{$data['productID']}'>";
echo "<input type='checkbox' class='SelectAll'>All";
echo "<label><input type='checkbox' class='selector' value='{$data['product1']}'>" . $data['product1']."</label>";
echo "<label><input type='checkbox' class='selector' value='{$data['product2']}'>" . $data['product2']."</label>";
echo "</form>";
}
?>
You just need to Change it to
echo "<form id='form{$data['productID']}' method='post' action=' ' data-checktable='{$data['productID']}'>";
i.e. remove the extra '.' between the word form and the ID you wanted.

i have some problem in here. I have textbox value inside table, and when i clicked link "Valid", i can pass the textbox value to another page.
This is my textbox code in table
echo "<form name='nomor' role='form' method='get'>";
echo "<input type='text' name='nomortempat' class='form-control input-sm'></input>";
echo "</form>";
This is my button
echo "<td class='center'>";
echo "<a class='btn btn-primary btn-sm' href='validasi.php?idorder=" . $row['id_order'] . "&pilih=" . $_GET['pilih'] . "'>
<i class='fa fa-check-square-o'>Valid</i></a>
echo "</td>";
Maybe someone can give me a solution, Thank you and have a nice day!!
In the page validasi.php add this:
$IDorder = $_GET['idorder'];
$Pilih = $_GET['pilih'];
Now you have two variables on validasi.php called IDorder and Pilih from your form
Or is it the nomortempat you want?
I think you can just add
$nomortempat = $_GET['nomortempat'];
to the validasi page and it should work. If I understand your code it should be sent
EDIT I was wrong, you need to add a sumbmit button to your form.
Add session start at the top of your pages: session_start();.
Then add this to your first page:
$_SESSION["idorder"] = $idorder;
$_SESSION["pilih"] = $pilih;
Then this code to your form:
echo "<form name='nomor' role='form' method='get'>";
echo "<input type='text' name='nomortempat' class='form-control input-sm'></input>";
echo "<input type='submit' name='submit' value='Submit'></input>";
echo "</form>";
Then on validasi page add this:
$nomortempat = $_GET['nomortempat']; // and:
$IDorder = $_SESSION["idorder"];
$Pilih = $_SESSION["pilih"];
Now you have all three values on validasi.php
with GET form, you could try this:
echo "<form name='nomor' action='action.php' role='form' method='get'>";
echo "<input type='text' name='nomortempat' class='form-control input-sm'></input>";
echo "<input type='submit' value='valid'>";
echo "</form>";
and in action.php page, to catch value in textbox name='nomortempat', code is below:
if (isset($_GET['nomortempat'])){
echo $_GET['nomortempat'];
}
Of course, you could add more input fields whenever you want to inside form with different names.
I would like some help printing what is in a certain textbox that was created by an echo command.
while($row = $result->fetch_assoc()){
$stringTest = $row['Price'];
$AssetId = $row['AssetId'];
echo "<center><div> <h3>Cost: ".$stringTest."";
echo '<form action="" method="get"><input type="text" name="uid">';
echo "</br><input class='myButton' type='submit' Name='Submit1' VALUE='I have bought'></a></form>";
/** ^ Input value I would like to get *//
echo "<a href='https://www.roblox.com/item-item?id=".$AssetId."' class='myButton'>Buy</a></h3></div></center>";
}
Use the code below to get the value from submit:
if(isset($_GET['Submit1'])) {
echo $_GET['Submit1'];
}
When the user clicks submit, it will echo the value of it.
If you want to print PHP element in a textbox you should put it in the value tag of the input
<?php
echo "<input type='text' value='" . $val . "'>";
?>
I need to display a list of elements and after each and every element a delete button is added dynamically. Whenever the user presses a delete button the corresponding element should be deleted and rest of the list should be shown.
I have written the following php code to accomplish this:
for($i=0;$i<count($b);$i++)
{
$a=$b[$i];
echo "<li>$b[$i]</li> ";
$p="remove"."$j";
echo "<form action='' method='post'> <input class='z' type='submit' name='$p' value='delete'> </form>";
$j++;
}
if($_POST['$p'])
{
//code for deleting
}
The problem is whenever the user presses the delete button only the last element added is getting deleted and rest of the buttons are not working.Please tell me how to detect which button has been pressed dynamically and delete the corresponding element using php.
Thank you
You need to associate each button with its respective element. You'll wanna do this dynamically with an id or hidden input or something.
for($i=0;$i<count($b);$i++)
{
$a=$b[$i];
echo "<li>" . $b[$i] . "</li> ";
$p="remove" . $i;
echo "<form action='' method='post'>";
echo "<input type='hidden' name='item' value='" . $i . "' />";
echo "<input class='z' type='submit' name='delete' value='delete'> </form>";
$i++;
}
if($_POST['delete'])
{
$item = $_POST['item'];
//code for deleting $item
}
You're putting each delete button in its own form - you could also add in a hidden input with the ID to remove?
echo "<form action='' method='post'>\n";
echo "<input type='hidden' name='toDelete' value='" .$i ."'>\n";
echo "<input class='z' type='submit' name='$p' value='delete'>\n";
echo "</form>\n";
You'd then look for the element to delete with:
if(isset($_POST['toDelete'])) {
// $_POST['toDelete'] has the index number of the element to remove
}
I have a table with 3 columns like so in index.php:
ID | StName | Inspect
_________________________________
1 Wisconsin INSPECT
2 Alabama INSPECT
3 Nebraska INSPECT
The right most column is a submit button which takes the user to a page called inspect.php. I want to send the corresponding ID column value to inspect.php when a user clicks the INSPECT button so that I can use that value inside inspect.php, how can I do this?
Currently I have:
//index.php
echo "<table border = 1>
<tr>
<td>ID</td>
<td>StName</td>
</tr>";
// go into a loop to create more rows -- omitted
echo "<tr>";
echo "<td>" . $resultArr[0] . "</td>";
echo "<td>" . $resultArr[1] . "</td>";
echo "<td> <form action='inspect.php' method='get'>
<input type='Submit' value='Inspect'>
</form>
</td>";
echo "</tr>";
echo "</table>";
$resultArr[0] contains the ID value I want to send to inspect.php
So add an input field inside the form with a name attribute which will be an index key name on inspect.php page
<form action='inspect.php' method='get'>
<input type='hidden' name="id" value='<?php echo $resultArr[0]; ?>'>
<input type='submit' value='Inspect'>
</form>
A better and simple way to go for this is without a submit, just use a hyperlink like
Inspect
And later process this id on inspect.php page
I think I got what you wanted to work. I am using different data in the array, but you should be able to change to your needs anyway.
On index.php:
$resultArr = array("dave","fff","erere");
echo "<table border = 1>
<tr>
<td>ID</td>
<td>StName</td>
</tr>";
// go into a loop to create more rows -- omitted
echo "<tr>";
echo "<td>" . $resultArr[0] . "</td>";
echo "<td>" . $resultArr[1] . "</td>";
echo "<td> <form action='inspect.php' method='get'>
<input type='hidden' name='id' value=' $resultArr[0] '>
<input type='submit' name='inspect' value='Inspect'> </td>";
echo "</tr>";
echo "</table>";
And on inspect.php:
if( $_GET['inspect']){
$name = $_GET['id'];
echo $name;
}
This outputs the value of $resultArr[0], which I think you wanted.
I have a for loop which actually displays a product name and several buttons like: Edit, Update , Cancel
For each product i am displaying , it will have its own set of Edir, Update, and Cancel button as below.
Paint Edit Update Cancel
I want to loop through the buttons so that for each category, I can perform a different action. I was thinking about using something like btn_edit1, btn_edit2 for the name of the button and use a for loop. 1, 2 are the category ids.
Maybe Im not clear enough. Sorry for that. Can anyone give me some suggestions?
for($i = 0; $i<count($obj_categories_admin->categories);$i++)
{
echo "<tr>";
echo "<td width='1500'>";
echo "<input type='text' name='name' size = '30' value='" . $obj_categories_admin->categories[$i]['name'] . "'/>";
echo "</td>";
echo "<td width='500'>";
echo "<input type='submit' value = 'Update details' name='submit_update_category_" .
$obj_categories_admin->categories[$i]['category_id'] . "'/>";
echo "</td>";
echo "<td width='500'>";
echo "<input type='submit' value = 'Edit Sub Categories' name='submit_edit_sub_" .
$obj_categories_admin->categories[$i]['category_id'] . "'/>";
echo "</td>";
echo "<td width='500'>";
echo "<input type='submit' value = 'Delete' name='submit_delete_category_" .
$obj_categories_admin->categories[$i]['category_id'] . "'/>";
echo "</td>";
echo "<td width='500'>";
echo "<input type='submit' value = 'Cancel' name='cancel'" . "'/>" ;
echo "</td>";
echo "</tr>";
}
I want to do something like
foreach($_POST as $key => $value)
{
}
so that when i click on a button it performs an action depending on the category_id.
I have tried this as suggested:
echo "<input type='submit' name='submit[add_category]'" .
"[" . $obj_categories_admin->categories[$i]['category_id'] . "]". " value='Add' />";
Now in my class, i have:
$a1 = $_POST['submit'];
$which_action = reset(array_keys($a1));
$which_category = reset(array_keys($a1[$which_action]));
But, i am getting the error : undefined index submit
I would give the name attributes of my submit buttons using following pattern:
name="submit[which_action][which_category]"
For example for your 'Update' button for category 123:
name="submit[update][123]"
When the user clicks any of the submit buttons, to determine which specific button the user has clicked you just need check for $_POST['submit'] in your PHP code:
$a1 = $_POST['submit'];
$which_action = reset(array_keys($a1));
$which_category = reset(array_keys($a1[$which_action]));
Well i would use something like this:
<fieldset>
<!-- product info -->
<input name="productName[paint]" />
<input name="productName[edit]" />
<input name="productName[delete]" />
<input name="productName[cancel]" />
</fieldset>
that way when you get it to the serverside everything will be nice and tidy in nested arrays.
