<\/code><\/p>\n\n echo \"<div class=\\\"form\\\"\"; \n echo \"<form action=\\\"index.php\\\" method=\\\"POST\\\">\";\n<\/pre>\n<\/p>\n
See it? The end of the first line does\u00adn\u2019t include a > to com\u00adplete the <div> tag. The result in IE\u2019s DOM:<\/p>\n
<\/code><\/p>\n\n <div class=\"form\" method=\"POST\" action=\"PRMT_process.php\" <form=\"\">\n<\/pre>\n<\/p>\n
The lack of a > caused the <form>\u2018s attrib\u00adut\u00ades to be con\u00adsumed by the pre\u00advi\u00adous <div>. Not sure how we end up with an attribute called \u2018<form\u2019 at the end, but it could be a quirk of IE\u2019s pars\u00ader stack that will\u00ading\u00adly con\u00adsumes garbage char\u00adac\u00adters and coerces them into attrib\u00adut\u00ades. Nasty. This meant there was\u00adn\u2019t a <form> tag open so the sub\u00admit but\u00adton had noth\u00ading to do.<\/p>\n
But that did\u00adn\u2019t fix it. I ripped out the con\u00adtents of the form and test\u00aded; no. Ripped out the code before the form includ\u00ading the boil\u00ader\u00adplate; no (inci\u00adden\u00adtal\u00adly, if a <form> is the first tag in the code \u2014 eg. no <body> \u2014 then the <form> is dropped on the floor by the pars\u00ader). Even\u00adtu\u00adal\u00adly I end\u00aded up with this testcase:<\/p>\n
<\/code><\/p>\n\n <body>\n <form action=\"index.php\" method=\"post\">\n <input type=\"submit\">\n <\/form>\n <\/body>\n<\/pre>\n<\/p>\n
Now at this point I was very, very con\u00adfused. Dumb\u00adfound\u00aded. Espe\u00adcial\u00adly since I\u2019d looked at the file in hex-view to make sure strange Uni\u00adcode char\u00adac\u00adters had\u00adn\u2019t invad\u00aded then checked the encod\u00ading and BOM. I re-typed each line. Still did\u00adn\u2019t work.<\/p>\n
I typed the con\u00adtents out in a sep\u00ada\u00adrate file and copy\/pasted over the top of the bro\u00adken one; still did\u00adn\u2019t work.<\/p>\n
I copied the orig\u00adi\u00adnal file and opened the copy; still did\u00adn\u2019t work. I vis\u00adit\u00aded \u2018witch\u00adcraft\u2019 on Wikipedia and researched human sac\u00adri\u00adfice, per\u00adformed a sacred rite involv\u00ading goats, 13-point stars and heavy breath\u00ading to the East; still did\u00adn\u2019t work.<\/p>\n
I opened the prop\u00ader\u00adties dia\u00adlog for the file on a whim:<\/p>\n
