vjmehra Posted May 8, 2012 Share Posted May 8, 2012 Hi, I have 2 radio button's within a table and need to pass this array. All other rows within my table can be sent as array's and captured using $_POST['field_name'][$ROW 1 value etc]. However for radio buttons this doesn't work. As an example, a standard textbox I can send an array using the following: echo "<td width='33%'><input type='Textbox' width='100%' id='test' name='test[]' value='" .$row['test']. "'></td>"; I can then capture it using: $test = $_POST['test'][$iLine]; This works, no problem, however for radio buttons, I can't use a static array name, as presumably it dumps all rows into the array, if I do this, only the last row has a checked button, hence I need to use the following (where $checked includes the logic to decide whether the button should be checked or not, this works correctly): echo "<input type='radio' name='".$row['venue_id']."[]' value='1'".$checked."/>P1" echo "<input type='radio' name='".$row['venue_id']."[]' value='0'".$checked2." />P2"; I tried using the following: var_dump($_POST[$row]['game_id'][$iLine]); But this just returns a null value. Any ideas? Link to comment https://forums.phpfreaks.com/topic/262272-radio-button-array/ Share on other sites More sharing options...
vjmehra Posted May 8, 2012 Author Share Posted May 8, 2012 I thought I'd knock up a quick simple form to show what I mean, not sure if this helps or not: <html> <head> <title></title> </head> <body marginheight="0" topmargin="0" marginwidth="0" leftmargin="0" style="margin:0;padding:0" bgcolor="#B0E0E6"> <h1></h1> <form action="" method="post"> <?php @ $db = new mysqli('xxx', 'xxx', 'xxx', 'xxx'); $query = "call sp_view_all_venues();"; $result = $db->query($query); $num_results = $result->num_rows; function db_result_to_array($result){ //--------------------------------------------------------------------- $res_array = array(); for ($count=0; $row = $result->fetch_assoc(); $count++) { $res_array[$count]=$row; } return $res_array; } //--------------------------------------------------------------------- echo "<input type='submit' id='btnupdate' name='btnupdate' value='Update & Delete' >"; $irow=0; while($row = $result->fetch_assoc()) { if($row['venue1']==1) $checked=" checked='checked'"; else $checked=''; if($row['venue2']==1) $checked2=" checked='checked'"; else $checked2=''; echo "<table><tr><td>"; echo "<input type='radio' name='".$row[venue_id']."[]' value='1'".$checked."/>".$row['venue_id']; echo "<input type='radio' name='".$row['venue_id']."[]' value='0'".$checked2." />P2"; echo "</td>"; $irow++; } echo "</tr></table>"; var_dump($_POST); ?> </form> </body> </html> the var dump shows: array(85) { ["btnupdate"]=> string(15) "Update & Delete" [92]=> array(1) { [0]=> string(1) "1" } [90]=> array(1) { [0]=> string(1) "0" } [91]=> array(1) { [0]=> string(1) "0" } [88]=> array(1) { [0]=> string(1) "0" } [89]=> array(1) { [0]=> string(1) "0" } [87]=> array(1) { [0]=> string(1) "0" } [80]=> array(1) { [0]=> string(1) "0" } [79]=> array(1) { [0]=> string(1) "0" } [78]=> array(1) { [0]=> string(1) "0" } [77]=> array(1) { [0]=> string(1) "0" } [76]=> array(1) { [0]=> string(1) "0" } [75]=> array(1) { [0]=> string(1) "0" } [74]=> array(1) { [0]=> string(1) "0" } [73]=> array(1) { [0]=> string(1) "0" } [72]=> array(1) { [0]=> string(1) "0" } [71]=> array(1) { [0]=> string(1) "0" } [70]=> array(1) { [0]=> string(1) "0" } [69]=> array(1) { [0]=> string(1) "0" } [68]=> array(1) { [0]=> string(1) "0" } [67]=> array(1) { [0]=> string(1) "0" } [66]=> array(1) { [0]=> string(1) "0" } [65]=> array(1) { [0]=> string(1) "0" } [64]=> array(1) { [0]=> string(1) "0" } [63]=> array(1) { [0]=> string(1) "0" } [62]=> array(1) { [0]=> string(1) "0" } [61]=> array(1) { [0]=> string(1) "0" } [16]=> array(1) { [0]=> string(1) "0" } [15]=> array(1) { [0]=> string(1) "0" } [14]=> array(1) { [0]=> string(1) "0" } [13]=> array(1) { [0]=> string(1) "0" } [12]=> array(1) { [0]=> string(1) "0" } [11]=> array(1) { [0]=> string(1) "0" } [60]=> array(1) { [0]=> string(1) "0" } [59]=> array(1) { [0]=> string(1) "0" } [10]=> array(1) { [0]=> string(1) "0" } [9]=> array(1) { [0]=> string(1) "0" } [8]=> array(1) { [0]=> string(1) "0" } [7]=> array(1) { [0]=> string(1) "0" } [6]=> array(1) { [0]=> string(1) "0" } [5]=> array(1) { [0]=> string(1) "0" } [56]=> array(1) { [0]=> string(1) "0" } [55]=> array(1) { [0]=> string(1) "0" } [54]=> array(1) { [0]=> string(1) "0" } [53]=> array(1) { [0]=> string(1) "0" } [52]=> array(1) { [0]=> string(1) "0" } [51]=> array(1) { [0]=> string(1) "0" } [50]=> array(1) { [0]=> string(1) "0" } [4]=> array(1) { [0]=> string(1) "0" } [3]=> array(1) { [0]=> string(1) "0" } [58]=> array(1) { [0]=> string(1) "0" } [57]=> array(1) { [0]=> string(1) "0" } [49]=> array(1) { [0]=> string(1) "0" } [48]=> array(1) { [0]=> string(1) "0" } [47]=> array(1) { [0]=> string(1) "0" } [46]=> array(1) { [0]=> string(1) "0" } [45]=> array(1) { [0]=> string(1) "0" } [44]=> array(1) { [0]=> string(1) "0" } [43]=> array(1) { [0]=> string(1) "0" } [42]=> array(1) { [0]=> string(1) "0" } [41]=> array(1) { [0]=> string(1) "0" } [40]=> array(1) { [0]=> string(1) "0" } [39]=> array(1) { [0]=> string(1) "0" } [38]=> array(1) { [0]=> string(1) "0" } [37]=> array(1) { [0]=> string(1) "0" } [36]=> array(1) { [0]=> string(1) "0" } [35]=> array(1) { [0]=> string(1) "0" } [34]=> array(1) { [0]=> string(1) "0" } [33]=> array(1) { [0]=> string(1) "0" } [32]=> array(1) { [0]=> string(1) "0" } [31]=> array(1) { [0]=> string(1) "0" } [30]=> array(1) { [0]=> string(1) "0" } [29]=> array(1) { [0]=> string(1) "0" } [21]=> array(1) { [0]=> string(1) "0" } [20]=> array(1) { [0]=> string(1) "0" } [19]=> array(1) { [0]=> string(1) "0" } [18]=> array(1) { [0]=> string(1) "0" } [17]=> array(1) { [0]=> string(1) "0" } [28]=> array(1) { [0]=> string(1) "0" } [27]=> array(1) { [0]=> string(1) "0" } [26]=> array(1) { [0]=> string(1) "0" } [25]=> array(1) { [0]=> string(1) "0" } [24]=> array(1) { [0]=> string(1) "0" } [23]=> array(1) { [0]=> string(1) "0" } [22]=> array(1) { [0]=> string(1) "0" } } Which is expected, but I have no idea how to extract and make sense of the submitted data....
