The ERP system is coming to an end, and a series of headers, such as delivery orders, return orders, contracts, and statements, are arranged for printing. HTML5 + CSS3 has become so popular. However, at the moment, the printing control based on CSS3 is still in the original tribe stage. Chrome, Firefox, Edge, and other simple @ pages are not supported completely. After some hard work, I finally found a good solution, that is, to output PDF, PHP captures the HTML code of the target, then output it to the specified parser, and then generate the final print format.
In fact, in this mode:
HTML5 + CSS3, only the adjustment of the output content, must ensure that the full feature support of CSS3 @ page is correct. In particular, the long article (contract) page, and long table automatic page (preferably thead and tfoot can be repeatedly displayed on pages ).
When previewing a PDF file, you can preview the layout before printing, and then directly print the output.
PDF files can be downloaded and backed up by users.
HTML content (PDF content) can be cached through the cache class library. you can adjust the cycle and compress the storage.
The problem was solved.
We recommend two available class libraries: Prince and wkhtmltopdf. Both are supported by cross-platform systems and are not embedded in php. Both products must be downloaded and installed on the official website. for windows, remember not to install them on the C drive. Otherwise, the installation will fail.
Php call:
Prince: download his official class library Prince for php. By the way, the Prince class library supports. net, Java, Python, Prel, and so on.
Snappy: this is a php composer extension developed by a foreign developer based on wkhtmltopdf. you can directly execute composer require knplabs/knp-snappy in your project. Snappy github address.
Prince and wkhtmltopdf are actually an html5 + css3 parser and fully support the printing feature of css3 @ page. And has the ability to generate PDF files. Among them, Prince is charged, but it provides free use of License. the disadvantage of the United States is that when a PDF preview is generated, there will be a P icon in the upper right corner of the first page, however, it disappears during printing.
Comparing the two, Prince provides better support for Chinese styles (maybe wkhtmltopdf is because my CSS style is incorrect and it is not targeted at @ media print) and modifies the Chinese font, wkhtmltopdf still uses the default output, while Prince is the font you specified.
The call code for both is simple.
Prince part:
convert_file_to_passthru('http://www.163.com');
Snappy part:
getOutput('http://www.163.com');
It's so cool that you don't have to worry about changing the print format any more.
No picture, no truth.
You can use HTML + CSS to print the file. the file is basically in the last format and can be completed in at most one hour. In this way, how many reports do you have? I use http: // erp/print/Register type/report id.ext's url,.html?request common html output; response is how fast the request outputs html pdf!
