pmorrison Posted March 4, 2006 Share Posted March 4, 2006 Hi,I am new to Javascript and am having a bit of difficulty. On my site, in order for a member to unsubscribe from an article, they go to the'Unsubscribe' page where they get a table of all of the articles that they are subscribed to. There is a table with each article, and a checkbox next to each article. For each checked checkbox it should send the value of the checkbox to stop_subscription.php.I have used the following javascript, I know there is something wrong with it, but dont know what:<script type="text/javascript"> function validate() { for(var i=0; i < document.table11.deletethis[].length; i++){ if(document.table1.deletethis[i].checked) stop_subscription.php?id="document.form1.deletethis[i].value" } }</script>Here are other bits of code I think might be relevant:<?php// Make table if member has specific injustice subscriptions $sql = "SELECT i.type, i.title , s.inj_id FROM inj_subscription s, injustices i WHERE s.member_id = '$user' AND i.inj_id = s.inj_id AND s.inj_id IS NOT null" ; $result = mysql_query($sql); $row = mysql_fetch_assoc($result) ; if ($row) { echo "<div><span>Specific Injustice Subsriptions:</span><br/>" ; $table_start ='<table width="90%" table name="table2" align="center" cellspacing="0" border="0"> <tr> <th width="20%">Type</th> <th width="70%">Title</th> <th width="10%"></th> <input type=button name="Unsubscribe" value="Unsubscribe" onClick="validate()" style="font-size:10px"/><p> </tr>'; echo $table_start; $rownum = 0; while($row) { $rownum++; $style = rowcolor($rownum); $table_rows = "<td id=\"td\" align=\"center\" style=\" $style ;padding:5px\" >" .$row['type'] . "</td>"; $table_rows .= "<td id=\"td\" align=\"center\" style=\" $style ;padding:5px\" >" . $row['title']. "</td> \n\t"; $table_rows .= '<td id="td" align="center" style="'.$style.';padding:5px;" >'."\n".'<input type="checkbox" name="deletethis[]" value="'.$row['inj_id'] . '"></td>'."\n\t"; echo "<tr>" . $table_rows . "</tr>"; $row = mysql_fetch_assoc($result) ; } echo '</table><Br/></div><br/>'; }?>I feel bad just pasting a large slab of code here, but I really have no idea where Im going wrong!Cheers,Paul Quote Link to comment https://forums.phpfreaks.com/topic/4111-going-through-a-checkbox-array/ Share on other sites More sharing options...
Barand Posted March 5, 2006 Share Posted March 5, 2006 You don't need the javascript.The form tag should have "action='stop_subscription.php' " and the checked checkbox values will be posted in the array $_POST['delete_this'].Store $user in a hidden form field so that too gets posted.In "stop_subscription.php"[code]$user = $_POST['user'];$injIDList = join (',' , $_POST['delete_this'] );[/code]then[code]DELETE FROM inj_subscription WHERE member_id = '$user' AND inj_id IN ($injIDList)[/code] Quote Link to comment https://forums.phpfreaks.com/topic/4111-going-through-a-checkbox-array/#findComment-14373 Share on other sites More sharing options...
pmorrison Posted March 5, 2006 Author Share Posted March 5, 2006 Ive had a go at changing this around, adding in the form tag, but I dont know if Ive put it in the right place, I feel Im out of my php depth! I Told a friend Id be able to do this for him, thinking it would be easy, but it appears I misjudged it!<?php require_once('member_auth.php') ; include_once('../includes/connect_db.php'); include_once('../includes/functions.php'); include('../header.php');?><?php //If user has applied for a subsciption, run this code // If all is OK, then make a subscription if ($_REQUEST['stop_subscription']==1) { if (count($_REQUEST['deletethis']) > 0) { // Split the subscriptions array so we can get the checkbox values. foreach ($_POST['deletethis'] as $sub=>$value) { // stop_subscription.php?id="$" } } }?><div id="title1" align="center"> <h3>Unsubscribe</h3> <?php// Make table if member has specific injustice subscriptions $sql = "SELECT i.type, i.title , s.inj_id FROM inj_subscription s, injustices i WHERE s.member_id = '$user' AND i.inj_id = s.inj_id AND s.inj_id IS NOT null" ; $result = mysql_query($sql); $row = mysql_fetch_assoc($result) ; if ($row) { echo "<div><span>Specific Injustice Subsriptions:</span><br/>" ; $table_start ='<table width="90%" table name="table2" align="center" cellspacing="0" border="0"> <tr> <form method="post" action="stop_subscription.php"> <th width="20%">Type</th> <th width="70%">Title</th> <th width="10%"></th> <input type="submit" name="Submit" value="Submit" style="font-size:10px"/><p> <input type="hidden" name="stop_subscription" value="1"/> </form> </tr>'; echo $table_start; $rownum = 0; while($row) { $rownum++; $style = rowcolor($rownum); $table_rows = "<td id=\"td\" align=\"center\" style=\" $style ;padding:5px\" >" .$row['type'] .

Barand Posted March 5, 2006 Share Posted March 5, 2006 All form elements, such as checkboxes and submit button need to be between <form>..</form> tags Quote Link to comment https://forums.phpfreaks.com/topic/4111-going-through-a-checkbox-array/#findComment-14448 Share on other sites More sharing options...
