ID: 32121 User updated by: jbeall at heraldic dot us Reported By: jbeall at heraldic dot us -Status: Feedback +Status: Open Bug Type: Arrays related Operating System: Linux PHP Version: 5.0.3 New Comment:
Actually I just had a possible epiphany - I am serializing the entire $_POST variable using WDDX and recovering on a subsequent page by deserializing the WDDX packet. I wonder if when WDDX deserializes an array, it stores everything at string indices, even if the indices are integers. Note that for convenience reasons the arrays in question start at [1], not [0]; that may be significant, I don't know enough about PHP's WDDX functionality to say. I will not be able to investigate this further for several days, but I will post back when I can.

I must not be truly understanding what is causing the problem (I am definitely having the problem that I cannot access array values from a form), but it must be something other than the name='fname[1]' field name. I was trying to simplify my code down to less than 20 lines for the post and I was missing $_REQUEST. What I may have to do is simply save is serialize the variable that I have that is causing me so much trouble and post a link to that. I'm really at a loss at this point as to what might be the cause since it is apparently not the form problem. Sorry for messing up the reproduce code. ------------------------------------------------------------------------ [2005-02-27 12:30:14] [EMAIL PROTECTED] <form method="post" action="index.php"> <input type="text" name="test[1]" value="bla-bla"/> <input type="submit"> </form> <? var_dump($_POST); var_dump($_POST['test'][1]); ?> Works fine here, debug your code. ------------------------------------------------------------------------ [2005-02-26 23:58:10] jbeall at heraldic dot us Mozilla autofilled some of the fields when I submitted this bug and so it had a completely unrelated/unhelpful summary. Hopefully it should be corrected now, sorry for the confusion... ------------------------------------------------------------------------ [2005-02-26 20:47:52] jbeall at heraldic dot us Description: ------------ If you give a form input a name that should be a numerically indexed array, such as <input type='text' name='fname[1]' /> It is not possible to directly access the variable via $_GET, $_POST, or $_REQUEST. Dumping the entire contents of the request using e.g. print_r reveals that the form data is submitted, but it cannot be accessed via e.g. $_POST['fname']['1'] or $_POST['fname'][1] Presumably this happens because the PHP engine is doing type juggling. When a request variable is submitted and looks like an array, the PHP puts it in an array and indexes the value at the string value '1'. However, when you try to access $_POST['fname']['1'] it sees that '1' could be an integer, converts to an integer transparently to the developer, and of course there is nothing stored at $_POST['fname'][1]. The data was stored at $_POST['fname']['1']. For whatever reason, embedding the variable in a string appears to solve the problem. E.g., "{$_POST['test'][1]}" works Reproduce code: --------------- echo "<pre>"; // So we can use \n for formatting echo <<<EOT <form method='GET' action='{$_SERVER['PHP_SELF']}'> <input type='text' name='test[1]' value='{$_REQUEST['test'][1]}'/> <input type='submit'/> </form> EOT; echo '('.gettype($test[1]).') value='.$test[1]."\n"; echo '('.gettype($test[1]).') value='.$test['1']."\n"; echo "But it works if we embed in a string ---> {$_REQUEST['test'][1]}\n"; var_dump($_REQUEST['test']); // Put a string variable in the textbox and submit. // If using GET method, URL might look like // bugTest.php?test%5B1%5D=any+string+here Expected result: ---------------- (string) value=any string here (string) value=any string here But it works if we embed in a string ---> any string here Array ( [1] => any string here ) Actual result: -------------- (NULL) value= (NULL) value= But it works if we embed in a string ---> any string here Array ( [1] => any string here ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32121&edit=1
