Is it possible to create barcode to submit HTML form and do MySQL update via PHP? I've never done something like that, but currently I'm building some application that will track job done in some Injection Mold company. Can I use mobile barcode scanner or we need dedicated barcode scanner? First, I thought about barcode that will automatically open URL in form like this
https://example.com/verif.php?pos=12&op=10&true=1
And that link will submit form I want. Or something like barcode scanner directly submit form without opening URL? I need advice.
Thanks!
I've worked with barcode scanners before. The barcode represents a string, and all that the scanner will do is read and paste it onto whatever format you have on the computer, in my case, it was on excel sheets, a field in an app, etc. Your scanner will come with a program where you can customize the action upon scanning.
You can definitely use a mobile scanner.
If you want it to submit a form without opening URL, you need to create a form submission platform, which needs to automatically submit and automate that process. Speed can be a key depending on how quickly you expect to scan.

I'm developing an web based Application using PHP & MySQL. My application requires the user to shot a Barcode Scanner to an AUTOFOCUS-ed field in my product entry form, after this AUTOFOCUS-ed field is filled with code shot form the BARCODE Scanner, the form presents a list of similarly coded products (THe products I'm scanning could have similar Barcodes but different Prices), out of which the user needs to select a particular product.
The Scanner I'm using is TVS BSC-101 STAR Scanner, which is most popular in India. The problem is that it is reading ENTER as appending code and I need to program it to append TAB (or something that emulates the TAB button on Keyboard) otherwise it is just not moving to the next field where the user based on the code scanned, gets a list of similarly coded products list.
Can anyone help me out in here, appreciate your help.
reading enter should trigger a page reload, isn't it?
if that's the case, implement a PHP function that read the barcode and output the similar ones.
otherwise you could inhibit the enter keypress via javascript and simulate a tab keypress
I have developed an attendance taking system with PHP and I am running it on localhost. The system is like this:
Suppose a student has a bar coded ID card and to take his attendance there is a barcode reader and the form I have developed. The barcode reader I have automatically pushes the submit button so as soon as I trigger the barcode reader's button, the value from the barcode is taken and after some processing some values are inserted into the database.
Now it is working fine, but the problem is every time I take the attendance I need to open up the form first and then take the attendance. (I need to take attendance several times a day.) I was wondering if there is any way to take the attendance without having to open up the form repeatedly.
If there is no solution for it, is it possible to keep the form page minimized and take attendances while someone is working on computer (doing something else)?
This depends on how your barcode reader works, mostly. I infer from your description that:
The barcode reader, when activated, sends the data and emulates Enter
The data is populated in the active input element, or, I assume, anywhere that keyboard characters are accepted. Can be tested by opening a text editor and seeing if the data is accepted followed by a newline.
Next, you have a web application, which doesn't run in the background. Technically it's still active on the browser even while minimized, but once minimized the browser is no longer the application with focus, and therefore the data doesn't go to it.
So you have two problems:
You need a way to get data from the barcode reader without affecting the current application. In other words, if someone is using a word processor, you don't want the barcode reader to suddenly insert random information in their work.
You need an application or service to "listen" to the barcode reader and interact with the database. You could write it so that it pops up a dialog or something in the event of a misread, incorrect attendee, etc.; however if the computer needs to be used for something else while attendance is being taken, that could be annoying.
Hopefully your barcode reader vendor has some information available to you which can help you solve problem 1. As for problem 2, I don't have any advice except to consider rewriting your application as a service or application that you can minimize.
I would imagine the scanner comes with software that in one way or another, would let you execute a command when a barcode scan event occurs.
then just craft the command
php attendance.php "...barcode data..."
I bet the scanner comes with documentation that would be at least somewhat helpful.
I've scoured the forums/web for this answer, but I've failed to come up with a solution.
I have a PHP based form that inputs form data onto a PDF generated by FPDF/FPDI (utilizing a pre-made template). That, in and of itself, is working just fine.
I have one version that is a simple quote; the user can input their email without adding in personal information if they're not ready to move forward. A PDF is created with their quote info. The question has come up on whether or not this generated PDF can have form input fields and a send button, that way the client can send along their newly completed form with their quote information.
Does anyone know of a utility out there that can generate a functional PDF with input fields/send button and also input data from a PHP form?
Whoever can help will be this girl's hero. I may even send you cookies.
i created a system using php..
on my system..there is a form...in that form has a submit button and view in pdf button ..
so my question is how to transform my php form into pdf form..user can view the form in pdf format even he did not submit the form yet and the details that he enter is appear in the pdf format form..please help me..
You'll need to create the form in Acrobat Pro, PDFpen Pro, FoxIt Reader (with appropriate add-ons), etc. In doing that, you can include a form control button that submits the form values to a URL as POST. Write a PHP script to receive that POST similar to an HTML form POST, and you're good to go.
From there, you just post the PDF to your site and let the visitor's PDF tools do the rest.
Note that form validation is also handled in-PDF. The tool you use to create the form will include a bunch of ready-to-go validations you can use (e.g., phone number or social security number), and if something's missing, you can incorporate JavaScript. Note that the JS runs in the PDF reader, not the browser, so it'll work even if the user has JS turned off.
If i have a website running php and apache, what do i need to be able to attach a scanner to it? How do i get the scanner to fill in a value on one of the webforms on my page?
I just did this for an application. It's actually simple. The scanner is just another input method and is, in fact, similar to a keyboard. When you scan the barcode the data is decoded by the scanner and sent to whatever application is waiting to receive it. In the case of a web-based application it would be a form, most likely with a textarea with focus. The data would then populate the textarea just as if someone had typed the barcode's data into it. The form is then submitted and processed normally.
Just make sure the textarea has focus or else the data will go either nowhere or to wherever focus is (which may be another form field or the address bar).
I have yet to figure how how to get the form to auto-submit upon the entry of the barcode data as the scanner does not send event information (i.e. submit) and special characters such as tab (\t) do not seem to work. (If anyone knows how to accomplish this I am very interested in knowing how it can be done).
For actually creating barcodes in PHP, you might want to have a look at:
http://www.mribti.com/barcode/
http://www.ashberg.de/php-barcode/
Usually, these scanners are equivalent to a keyboard input, so you just select the appropriate input point on the web page, scan, and then submit the form.
WASP makes a line of barcode scanners that simply plug into USB or PS/2 inputs and basically convert the barcode scanned into the characters, just like a user typed them using a keyboard. They have an FAQ and help videos that may be of assistance, too.
When designing your web app, depending on how users interact with it, you can use Javascript to move focus from one field to another so that a user can scan barcodes sequentially without having to click on the field where the characters go. (Similar to how some forms move focus as you type data with a known length, such as a zip code or phone number.)
You can try this:
I think this is the best way to integrate barcode in web application
using php.
integrating barcode scanner into php application?
I hope this link is usefull to all.
Using an autofucus input is the better way. You just have to make sure that you create a for and add autofocus to the input box. So each time a user scans any item, the form is automatically submitted. So just give the form an id and handle the data easily with jquery
