Planned stable release date? PHP 7 support? about tc-lib-pdf

[Ohda]

Hello. Any update on an possible release date ?

[EduVillas]

What about php 8.0 ???

[nicolaasuni]

Hi, thank you for the help offers.
People can contribute either via PR or sending donations following the link in the README.md.

The overall project is almost complete but I struggle to find the time to complete the core functions in the main library.
All the dependency libraries are complete and some of them can also be used with the old TCPDF library:

• tc-lib-barcode
• tc-lib-color
• tc-lib-pdf-image
• tc-lib-pdf-font
• tc-lib-file
• tc-lib-pdf-encrypt
• tc-lib-unicode-data
• tc-lib-unicode
• tc-lib-pdf-page
• tc-lib-pdf-graph

The main library (tc-lib-pdf) can now build a blank page.
The aim is to complete the Output.php file first and then start adding the basic functions to print a text cell, etc.

In the Output file the incomplete functions have an empty body and they are marked with a @todo comment.

That is best project for PDF in php, do you need some help with it?

[mcgreevyd]

Any news on this?

[divinity76]

@semaex a 3rd party patch is available, but @nicolaasuni has indicated that no patches will be accepted upstream because TCPDF is "frozen"

[xperseguers]

@gerardreches Using with PHP 7.4 for a long time, not facing any problems with my use cases.

[xperseguers]

I had a reference to that repository but after double-checking, I'm actually using "tecnickcom/tcpdf": "dev-main", in my composer.json files, so the development branch of that package.

[nicolaasuni]

The old library should support PHP7, I merged some changes recently.
The new library is currently progressing very slowly because I am quite busy but more than 90% of the code is there (now spread across independent libraries).

[nicolaasuni]

Note that the current version of the new library has an example that generates a blank page!
There are some ready methods also to add fonts, graphics and barcodes but some essential methods for text are still missing.

[divinity76]

i have been using the old library on php 7.0 in production for months without (php7-related) problems, so yeah, it supports PHP7 just fine.

[MacGritsch]

Thank you for the information.
So its best to use the old version.
Are there still plans to finish this new version?

thank you for all your efforts and best regards

[divinity76]

@mklemarczyk the current status, the way i see it (and use it) is: the old lib is production ready, the new lib is not. so yeah, unless you're planning on helping out the development of the new version, use the old version for now.

Hi,

I have a project with old tecnickcom/tcpdf and with new php 7.2 version it doesn't work anymore.

each() method used in tcpdf.php file is deprecated.

@nicolaasuni is possible to update old version? I know is not manteined anymore but I think is a small bug and the new version is not ready yet...

Thanxs for this good library ;)

[MacGritsch]

@semaex you can simply apply this patch:

Thanxs MacGritsch. I know how to solve this bug but I need the changes persist in oficial repo because my deploy system with composer downloads directly from authors repo.

Any ideas?

[MacGritsch]

@semaex you could create a (private) fork, apply the patch and use that fork in your composer files.

[semaex]

@MacGritsch @divinity76 Thanxs for ideas, I'll do this ;)

[pyrographics]

Looking forward to the release of the new library. What is the best way to troubleshoot PDF corruption using the old tcpdf? Sometimes the PDF exports correctly and sometimes it is corrupted. No error is generated so I'm stuck as to what is causing it.

[xperseguers]

Could someone tell me where to look for some basic up-to-date samples? https://tcpdf.org/examples/ are all based on an older version of the library, example in this project only shows creating a blank page, but nothing regarding adding some text, adding some graphics, adding a barcode, ...

[extcode]

@semaex you can also use the official repository and use https://github.com/cweagans/composer-patches to patch the files with composer.

[semaex]

thanxs to everyone ;)

[gnurob]

Are there ways to offer some support to this project besides coding?

[kdruzycki]

Any news? :)

[connorhu]

@nicolaasuni Do you have any list of release blocker tasks?

[rabol]

@nicolaasuni let us know how we can help, please

[mklemarczyk]

Super news, I will take a look in a free time to try to help with finishing the library.

[gerardreches]

I need to generate PDF certificates on my site using PHP (using PHP 7.4). Does someone know if this library already works or if the old one is compatible with PHP 7.4?

Thanks!

[gerardreches]

@gerardreches Using with PHP 7.4 for a long time, not facing any problems with my use cases.

Hi Xavier!

Are you talking about this library (the new one under development) or the old one (stable)?

Thanks!

[gerardreches]

I had a reference to that repository but after double-checking, I'm actually using "tecnickcom/tcpdf": "dev-main", in my composer.json files, so the development branch of that package.

I will give it a try then, thank you!

Thanks!

have you a solution ??

[xperseguers]

@mahouha Please read my answer following the question, from April last year. in short: it works! just use dev-main in your composer.json

[MacGritsch]

Old version also works with PHP 8.x
