Using PHP and Javascript in onblur function -
so have form:
<form enctype="multipart/form-data" action="cgi-bin/upload.cgi?upload_id=" method="post" onsubmit="return startupload(this);" target="xupload"> <table> <tr> <td class="first"><span class="right">upload file: </span></td> <td class="second"><input name="file_1" type="file" onchange="checkext(this.value)" accept=".mp4, .avi, .wmv, .mov, .camrec, .flv, .zip, .rar"></td> <td class="third"><span class="left">(required)</span></td> </tr> <tr></tr> <tr><center><h2>video information</h2></center></tr> <tr></tr> <tr> <td class="first"><span class="right">your name: </span></td> <td class="second"><input type="text" name="name"></td> <td class="third"><span class="left">(preferred)</span></td> </tr> <tr> <td class="first"><span class="right">series id: </span></td> <td class="second"><input id="series_id" type="text" name="series_id" placeholder="you should have been given admin"></td> <td class="third"><span class="left">(preferred)</span></td> </tr> <tr> <td class="first"></td> <td class="second"><span id="series_id_check">enter you're series id above , change</span></td> <td class="third"></td> </tr> <tr> <td class="first"><span class="right">title: </span></td> <td class="second"><input type="text" name="title"></td> <td class="third"><span class="left">(preferred)</span></td> </tr> <tr> <td class="first"></td> <td class="second center"><small>please use "<span style="color:#9c0000"><br></span>" make new line</small></td> <td class="third"></td> </tr> <tr> <td class="first"><span class="right">description: </span></td> <td class="second"><textarea name="desc"></textarea></td> <td class="third"><span class="left">(preferred)</span></td> </tr> <tr> <td class="first"><span class="right">guests: </span></td> <td class="second"><input type="text" name="guests"></td> <td class="third"><span class="left">(optional)</span></td> </tr> <tr> <td class="first"><span class="right">additional tags: </span></td> <td class="second"><input type="text" name="tags"></td> <td class="third"><span class="left">(comma separated - optional)</span></td> </tr> </table> <input type="submit" name="submit" value="upload file"> </form> which use upload videos web hosting server. want able change text in series_id_check span javascript uses php arrays... here's php use populating arrays mysql (i know depreciated web hosting php 5.3 installed , depreciated 5.4):
$sql1 = mysql_fetch_assoc(mysql_query("select count cnt series")); $count = $sql1['cnt']; $gamearray = array($count - 1); $namearray = array($count - 1); $idarray = array($count - 1); ($i = 0; $i < $count; $i++) { $sql2 = mysql_fetch_assoc(mysql_query("select id,game,name series id='{$i}'")); $gamearray[$i] = $sql2['game']; $namearray[$i] = $sql2['name']; $idarray[$i] = $sql2['id']; } i know connects database fine i've got die statement when tries connect
the javascript is:
var id = "series_id"; document.getelementbyid("series_id").onblur = function() { var value = document.getelementbyid(id).value; var gamearray = new array(<? echo implode(',', $gamearray); ?>; var namearray = new array(<? echo implode(',', $namearray); ?>; var idarray = new array(<? echo implode(',', $idarray); ?>; if (inarray(value,idarray) { var id = parceint(value); var game = gamearray.indexof(id); var name = namearray.indexof(id); var input= "you've inputted id game: " + game + " series: " + name; document.getelementbyid("spawn_series_id_check").innerhtml = input; } }); function inarray(var input, var array) { var count = array.length; var returnval = false; (var = 0; < count; i++) { if (array[i] == input) { returnval = true; } } return returnval; } basically text in series_id_check doesn't change. tell me how fix it
you should consider using json handle these data.
$result = mysql_query("select id,game,name series"); $count = count($result); $series = array(); while ($row = mysql_fetch_assoc($result)) { $series[$row['id']] = array('game' => $row['game'], 'name' => $row['name']); } and @ js:
document.getelementbyid("series_id").onblur = function() { var series = '<?php echo json_encode($series); ?>'; var id = parseint(this.value, 10); if (undefined !== series[id]) { var game = series[id]['game']; var name = series[id]['name']; var message = "you've inputted id game: " + game + " series: " + name; document.getelementbyid("spawn_series_id_check").innerhtml = message; } }); i haven't tested code, way should go.
