将PDF表单数据接收到PHP中 [英] Receiving PDF form data into PHP
问题描述
所以我一直在网上寻找几个小时,因为我认为这是一个非常简单的答案,但我似乎找不到.
So I have been looking online for several hours for what I think is a very simple answer but I can't seem to find it.
我试图了解PDF表单数据提交的工作方式.我的目标是读取从我在PHP脚本中设置的PDF表单提交的表单数据.我希望我的PHP脚本能够解析表单数据并将其插入到我的SQL数据库中.
I am trying to understand how PDF form data submitting works. My goal is to read form data submitted from a PDF form that I set up into my PHP script. I want my PHP script to parse the form data and plug it into my SQL database.
我遇到的障碍是如何接收文件以便可以对其进行解析?
The roadblock I am running into is how do I receive the file so I can parse it?
提交的文件的文件名是什么?
What is the filename of the file that gets submitted?
我在PDF表单上设置了提交按钮,可以将其导出为FDF,HTML或XFDF,但是我只是试图将数据转换为字符串或将内容以某种方式导入PHP,但我没有知道怎么做.
I have my submit button setup on my PDF form and I can export it in FDF, HTML, or XFDF, but I am just trying to get the data into a string or get the contents somehow into PHP but I don't know how.
如果我尝试:
$ fileFromPDF = file_get_contents('file.txt',true);
$fileFromPDF = file_get_contents('file.txt', true);
我仍然需要文件名,并且我不知道从PDF表单提交的文件名.如何获得此文件的名称?它甚至是一个文件还是仅一行xml?如果只是一行XML,我怎么收到这个消息?
I still need the name of a file, and I don't know the name of the file that is being submitted from the PDF form. How do I get the name of this file? Is it even a file or just a line of xml? If it is just a line of XML, how do I receive this?
我们将不胜感激,或者如果有人可以向我指出正确的方向,那么
Any help would be appreciated or if someone could point me in the right direction.
推荐答案
function ArrayFromHttpPut() { # assume a simple PUT, like a PDF form submission
$arrRtn = array(); # init result
$strInp = file_get_contents('php://input'); # PUT data comes in on StdIn, not in GET
$arrInp = explode("\r\n", $strInp, 2); # break input into array by only the first CrLf
$strBnd = $arrInp[0]; # first line of input is content boundary
$strInp = $arrInp[1]; # proceed with remainder of input
$arrInp = explode($strBnd, $strInp); # break input into array by content boundary
foreach ($arrInp as $idxInp => $strInp) { # scan input items
$arrItm = explode("\r\n\r\n", $strInp, 2); # break each item into array by only the first double-blank line
$arrItm[0] = trim($arrItm[0]); # drop spurious leading and trailing
$arrItm[1] = trim($arrItm[1]); # blank lines from both parts
$arrItmNam = explode('=', $arrItm[0]); # break item name away from Content-Disposition wording
$strItmNam = str_replace('"', '', $arrItmNam[1]); # get item name without its enclosing double-quotes
$strItmVal = $arrItm [1] ; # get item value
$arrRtn[$strItmNam] = $strItmVal; # append (item-name => item-value) to output buffer
} # done with scanning input items
return $arrRtn; # pass result back to caller
} # ArrayFromHttpPut
