php - input hidden value limit in html -
i trying put entire 20kb jpg file content in input hidden value, when receive data 4kb file. problem ?
i using following code read jpg server , upload server.
<?php $filename = "filetocopy.jpg"; $filedata = file_get_contents($filename); file_put_contents("filetocopy1.jpg", $filedata); echo "<!doctype html public \"-//w3c//dtd html 4.0 transitional//en\"><html><head><title></title>"; echo "<script language = "."javascript"." type"."test/javascript".">"; echo "function dosubmit() {"; //alert('function called.'); echo "document.forms[\"postjsform\"].submit();"; echo "}"; echo "</script>"; echo "</head>"; echo "<body onload='dosubmit();'>"; echo "<!-- start of form -->"; echo "<form id=\"postjsform\" action=\"postjs2.php\" method=\"post\">"; echo "hidden data: <input type=\"hidden\" name=\"hiddendata\" value=" . $filedata . ">"; echo "<br>"; echo "</form>"; echo "<!-- end of form -->"; echo "</body></html>"; ?>
since didn't post html form, imagine problem there.
for example, using method="get"
instead of method="post"
, running url length limitation.
two things of here: truncating data, , it's not php.
