      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content.

There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

edit button on php table created from sql DB

Recommended Posts

Weiss    0

Hi!

Im making a php script which goes over an MySQL DB and present the Db as Table (its actually a db of customers where there's info of their ship address, phone, etc).

so the php script fetch array and take 1 row at a time, and ofcours go thru all the elements in the DB and present it in a table.

I wish i can make an EDIT button at the end of each row where the user can press it and it will move it to another (already made) edit user php script with the row Customer number. 

of cours i can end each line with a button but how can i make it so that after all the table has been printed out (maybe 250 rows) each button at the end of the row will lead to the edituser.php with the specific row customer number?

any idea? thanks in advance

dsonesuk is referring to using <a> tag. Like:

<a href="edituser.php?cust_id=n">Edit User</a>

You haven't added a index reference name, just the value

edituser.php?cust_id=n

filename with querystring initialiser : index name : value ($order_mum)

So when you need to read value of specific name index

$this_order = $_GET['cust_id'];

Actually No, there are several ways to do this, and I did not which had been chosen, but the how the querystring and value are used is the important part to get it to work.

when i try doing this:

echo '<td><form method="get" action="findorder.php"><input type="submit"  name="testing" value="Edit" /></form></td>';

i get redirected to: http://localhost/logitech/findorder.php?testing=Edit

..

i can use $_GET['testing'] but it will give me whaever in the value which is "Edit".. i cannot change the value because it will change the writing on the button

Last time i checked GET is for query strings (using <a> tag, although can be applied to form via method get) which is what you mentioned in your post. But okay man.

When a get form is submitted it would produce an querystring also

You are not adding querystring to form action, example

echo '<td><form method="get" action="findorder.php?order_num='.$order_num.'"><input type="submit"  name="testing" value="Edit" /></form></td>';

In findorder.php

$this_order = $_GET['order_num'];  //would retrieve value of $order_num

same as

$this_test = $_GET['testing'] // would retrieve value of 'Edit'.

OR add to hidden input, like I said there are several ways to do this

echo '<td><form method="get" action="findorder.php"><input type="hidden"  name="order_num" value="'$order_num.'" ><input type="submit"  name="testing" value="Edit" /></form></td>';

Well if i do this i get directed to the findorder.php. my url shows: http://localhost/logitech/findorder.php?testing=Edit

when i echo $this_order i get nothing

when i echo $this_this i get: Edit

Try last suggestion I added in my post before this one, the previous will work if changed to post method but you would use

$this_order = $_GET['order_num'];  //would retrieve value of $order_num

$this_test = $_POST['testing'] // would retrieve value of 'Edit'

because you are using get the input value will overwrite the one set in action (unless you add a '&' at end to include both)

	while ($row = mysqli_fetch_array($data)) {
		echo '<tr>';
		echo '<td>'.$row['order_num'].'</td>';
		echo '<td>'.$row['cust_name'].'</td>';
		echo '<td>'.$row['store_name'].'</td>';
        echo '<td><form method="get" action="findorder.php?order_num='.$order_num.'"><input type="submit"  name="testing" value="Edit" /></form></td>';
          
          }

doesnt work thanx very much though dsonesuk, posted the code maybe someone will be able to fix this :P

echo '<form method="post" action="findorder.php?order_num=' . $order_num . '"><input type="submit"  name="testing" value="Edit" /></form>';

Will work with

        $this_order = $_GET['order_num'];  //would retrieve value of $order_num

        $this_test = $_POST['testing']; // would retrieve value of 'Edit'.

        echo $this_order . '<br>' . $this_test;

IF get method the input will overwrite the querystring set in action, if you wish to use GET method you would have to do it this way

echo '<td><form method="get" action="findorder.php"><input type="hidden"  name="order_num" value="'$order_num.'" ><input type="submit"  name="testing" value="Edit" /></form></td>'; 

with

        $this_order = $_GET['order_num'];  //would retrieve value of $order_num

        $this_test = $_GET['testing']; // would retrieve value of 'Edit'.

        echo $this_order . '<br>' . $this_test;

IF going this way it would be better to set form AS POST method, so the naming and values do not appear in address bar of browser

:| still not working.. i dont understand how can i use post method and comine it with $_GET on the second script. ANYWAY, maybe A HREF is a better option but is there a way to let the user click on <a href> and send it with $order_num data?

 

thanks very much again for your your time
