PHP - Setting A Default On A Drop Down Box
having a problem figuring out how to change the default on a drop down box to equal the users current timezone. So when they view it the drop box default is showing what their setting is atm. The problem is the value is differant from whats displayed. Is it possible to some how say if users time offset is equal to a option value set selected=""> to yes.
if not what is the idea behind this? Cant find a guide showing an example In other drop down boxes where the value is the same as whats displayed I just simply created another value field at the top of the list and echo it in. Code: [Select] <select name="gmt"> <option value="-28800">(GMT -0800) Pacific Time </option> <option value="-25200">(GMT -0700) Mountain Time </option> <option value="-21600">(GMT -0600) Central Time</option> <option value="-18000">(GMT -0500) Eastern Time </option> </select> Similar TutorialsHi. I have drop down boxes for date and time that work. The year is a problem because I am using variables instead of fixed values. Code: [Select] <select name="Year" style="width:60px"> <option value="2010" >Test <option value="<?=$ThisYear?>" <? if ($Year == "<?=$ThisYear?>"){?> SELECTED <?}?> ><?=$ThisYear?> <option value="<?=$NextYear?>" <? if ($Year == "<?=$NextYear?>"){?> SELECTED <?}?> ><?=$NextYear?> </select> <select name="Hour" style="width:50px"> <option value="10" <? if ($_SESSION["Hour"] == "10"){?> SELECTED <?}?> >10 <option value="11" <? if ($_SESSION["Hour"] == "11"){?> SELECTED <?}?> >11 <option value="12" <? if ($_SESSION["Hour"] == "12"){?> SELECTED <?}?> >12 <option value="13" <? if ($_SESSION["Hour"] == "13"){?> SELECTED <?}?> >13 <option value="14" <? if ($_SESSION["Hour"] == "14"){?> SELECTED <?}?> >14 <option value="15" <? if ($_SESSION["Hour"] == "15"){?> SELECTED <?}?> >15 <option value="16" <? if ($_SESSION["Hour"] == "16"){?> SELECTED <?}?> >16 <option value="17" <? if ($_SESSION["Hour"] == "17"){?> SELECTED <?}?> >17 <option value="18" <? if ($_SESSION["Hour"] == "18"){?> SELECTED <?}?> >18 <option value="19" <? if ($_SESSION["Hour"] == "19"){?> SELECTED <?}?> >19 <option value="20" <? if ($_SESSION["Hour"] == "20"){?> SELECTED <?}?> >20 </select> however this works Code: [Select] <select name="Year" style="width:60px"> <option value="2010" >Test <option value="<?=$ThisYear?>" <? if ($Year == "2011"){?> SELECTED <?}?> ><?=$ThisYear?> <option value="<?=$NextYear?>" <? if ($Year == "2012"){?> SELECTED <?}?> ><?=$NextYear?> </select> Can anyone help with this please TIA Desmond. Okay, so, here's my dilemma. I'm wanting to have it so someone can edit an item in the database, but it is a dropdown menu for the options to choose from. How do I make it so that the option that the item currently is is what the default showing is? For instance, if the item is for a "warrior", it will show warrior already in the dropdown menu. However, I could go to the dropdown menu and select a different option if I wanted. The {{class}} doesn't seem to give that default. Right now, it just defaults to "All" regardless of what the item truly goes to, such as "warrior". Thanks in advance!! Here's what I have for the coding: <tr><td width="20%">Class:</td><td><select name="class" value="{{class}}"> <option value="1" {{class1select}}>All</option> <option value="2" {{class2select}}>Alchemist</option> <option value="3" {{class3select}}>Assassin</option> <option value="4" {{class4select}}>Dark Arts</option> <option value="5" {{class5select}}>Dark Paladin</option> <option value="6" {{class6select}}>Entertainer</option> <option value="7" {{class7select}}>Hunter</option> <option value="8" {{class8select}}>Mage</option> <option value="9" {{class9select}}>Monk</option> <option value="10" {{class10select}}>Paladin</option> <option value="11" {{class11select}}>Pirate</option> <option value="12" {{class12select}}>Priest</option> <option value="13" {{class13select}}>Psion</option> <option value="14" {{class14select}}>Scholar</option> <option value="15" {{class15select}}>Thief</option> <option value="16" {{class16select}}>Warlock</option> <option value="17" {{class17select}}>Warrior</option> </select></td></tr> I am working on a project that uses a drop down list to chose the category when inserting new data into the database. What I want to do now is make the drop down list default to the chosen category on the list records page and the update page. I have read several tutorials, but they all say that I have to list the options and then select the default. But since it is possible to add and remove categories, this approch won't work. I need the code to chose the correct category on the fly. There are two tables, one that has the category ID and category name. The second table has the data and the catid which is referenced to the category id in the first table. Code: [Select] -- -- Table structure for table `categories` -- DROP TABLE IF EXISTS `categories`; CREATE TABLE IF NOT EXISTS `categories` ( `id` int(11) NOT NULL AUTO_INCREMENT, `categories` varchar(37) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=40 ; -- -------------------------------------------------------- -- -- Table structure for table `links` -- DROP TABLE IF EXISTS `links`; CREATE TABLE IF NOT EXISTS `links` ( `id` int(4) NOT NULL AUTO_INCREMENT, `catid` int(11) DEFAULT NULL, `name` varchar(255) NOT NULL DEFAULT '', `url` varchar(255) NOT NULL DEFAULT '', `content` varchar(255) NOT NULL DEFAULT '', PRIMARY KEY (`id`), KEY `catid` (`catid`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=35 ; Then is the list records file, I have Code: [Select] <?php include ("db.php"); include ("menu.php"); $result = mysql_query("SELECT categories FROM categories") or die(mysql_error()); while ($row = mysql_fetch_array($result)) { $categories=$row["categories"]; $options.= '<option value="'.$row['categories'].'">'.$row['categories'].'</option>'; }; $id = $_GET['id']; $query="SELECT * FROM links ORDER BY catid ASC"; $result=mysql_query($query); ?> <table width="65%" align="center" border="0" cellspacing="1" cellpadding="0"> <tr> <td> <table width="100%" border="1" cellspacing="0" cellpadding="3"> <tr> <td colspan="7"><strong>List data from mysql </strong> </td> </tr> <tr> <td align="center"><strong>Category ID</strong></td> <td align="center"><strong>Category ID</strong></td> <td align="center"><strong>Name</strong></td> <td align="center"><strong>URL</strong></td> <td align="center"><strong>Content</strong></td> <td align="center"><strong>Update</strong></td> <td align="center"><strong>Delete</strong></td> </tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td> <SELECT NAME=catid> <OPTION>Categories</OPTION> <?php echo $options; ?> </SELECT> </td> <td><? echo $rows['catid']; ?></td> <td><? echo $rows['name']; ?></td> <td><a href="<? echo $rows['url']; ?>"><? echo $rows['url']; ?></a></td> <td><? echo $rows['content']; ?></td> <td align="center"><a href="update.php?id=<? echo $rows['id']; ?>">update</a></td> <td align="center"><a href="delete.php?id=<? echo $rows['id']; ?>">delete</a></td> </tr> <?php } ?> </table> </td> </tr> </table> <?php mysql_close(); ?> So, how do I get this code Code: [Select] $result = mysql_query("SELECT categories FROM categories") or die(mysql_error()); while ($row = mysql_fetch_array($result)) { $categories=$row["categories"]; $options.= '<option value="'.$row['categories'].'">'.$row['categories'].'</option>'; }; <SELECT NAME=catid> <OPTION>Categories</OPTION> <?php echo $options; ?> </SELECT> to give me an output that will be something like if catid exactly matches categories.id echo categories.categorie ??? so far everything I have done produces either a default category of the last category, the catid (which is a number), all of the categories (logical since catid will always be = id, or nothing. How do I get just the category name? I will keep reading and try to figure this out, but any help would be greatly appreciated. Thanks in advance How to define default folder. For example I have folder images and in that folder specific image. In the root directory I have index.php with Code: [Select] <?php require_once("public/includes/header.php"); ?>and in index.php there are links which goes to different folder: Code: [Select] <a href="public/sajt/kategorija.php?id=<?php echo $id; ?>">which also have header.php, but there is no image. How to make default folder for image, or some similar solution? I have a few dropdown forums and would like it to select the current values that are requested. Code: [Select] global $filename,$fileid,$filetype,$filedir,$fileby; global $months,$pg; echo "<h2>Search Files</h2>"; echo "<p>"; echo "<form name = 'File_Search' action = '#' method = 'POST'>"; echo "<table border=\"0\" width=\"100%\"><tr>"; echo "<td>File Name<br><input type = 'text' name = 'name'></td><td>File Type<br><select name = 'type'> <option value = '0'>All Types</option> <option value = 'o'>Official Files</option> <option value = '1'>Quests</option> <option value = '2'>Graphic/Spritesheets</option> <option value = '3'>Entity/Scripts</option> <option value = '4'>Sound/Music</option> <option value = '5'>QuestPack/Programs</option> <option value = '6'>Miscellaneous</option> </select></td>"; echo "<td>Order By<br><select name = 'order'> <option value = '0'>Last Updated</option> <option value = '1'>ID</option> <option value = '2'>Name</option> <option value = '3'>Downloads</option> <option value = '4'>Rating</option> <option value = '5'>Points</option> <option value = '6'>Random</option> </select></td>"; echo "<td>Acending?<br><select name = 'dir'><option value = '0'>False</option><option selected value = '1'>True</option></select></td>"; echo "</tr><tr><td rowspan = '4'><input type = 'submit' name = 'search' value = 'search'></td></tr></table></form>"; echo "</p>"; So if the $filetype equals 2 I want the dropdown box to show "Graphic/Spritesheets" by default. BTW Official Files is not actually a type so that's why I chose to give it a small letter o and will work the same way as All Types but run a different function. $fileby is used for the OrderBy field. $filedir is for the Acending field. The other data is for the other parts of the script. If you like you can give advice on the name's default because you may have a better method then what I have in my head. How do I set the date format so that it's always going by the UTC date? I've used: Code: [Select] date_default_timezone_set('UTC'); but, when I change my date on my computer, the date changes on the website. This is really confusing me, googled different ways for like 10/20 minutes and can't find anything. If anyone can help it'd be great, Thanks, Andy. I am using this php code <?php echo $_GET['CiFrame']; ?> to check the url for the variable CiFrame, this allows me to link to a page through my page containing the iframe. Here is my iframe code. <iframe name="CiFrame" width="727" height="805" src="<?php echo $_GET['CiFrame']; ?>" scrolling="auto" frameborder="0"></iframe> The problem is that if the url does not contain a variable the iframe will not open a page. How can i set a default variable if one is not provided? Thank You In a Switch statement, can you give the Default: a specific name, maybe like this... switch ($resultsCode){ // Missing Primary Key. case 'COMMENT_MISSING_KEYS_2050': echo '<h1>System Error</h1>'; echo '<p>A Fatal Error has occurred.

Ok, i can't understand whats wrong with the DATE field in MySQL and PHP. I have a form in PHP witch has 3 birth day dropdown menus that looks like this (YYYY-MM-DD). An in my database i have a birth_day colum with DATE as type and i've tried to set the default value to "None" and "0000-00-00" but nothing works. Everytime i try to input something (e.g. 1993-16-05) i get this error: Incorrect date value: '05' for column 'birth_day' at row 1 I've tried to set the value for the "Day" dropdown in the PHP form to both 5 and 05 but still nothing, what am i doing wrong? My 1st try practice uploading file to the server and it was successful. Now I wonder how can I set a default file name to the file that will be uploaded and overwrite the existing one. I have tried experimenting on the code but I can't get it to work. Here's my simple code.. edit_logo.php Code: [Select] <?php <form enctype="multipart/form-data" method="post" action="uploaded_logo.php"> <input type="hidden" name="MAX_FILE_SIZE" value="100000" /> <tr> <td>Choose a Logo to Upload: </td> <td><input name="uploaded_file" type="file" /></td> </tr> <tr> <td> </td> <td><input type="submit" value="Upload File" name="submit>"</td> </tr> </form> ?> uploaded_logo.php Code: [Select] <?php if($_FILES['uploaded_file']["type"] == "image/gif") { $target_path = "logo/"; $target_path = $target_path. basename($_FILES['uploaded_file']['name']); if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path)) { echo "<span class=\"error_validation\">The Logo has been successfully changed!<br></span>"; echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>"; } else { echo "<span class=\"error_validation\">There was an error uploading the logo. Pls. try again.<br></span>"; echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>"; } } else { echo "<span class=\"error_validation\">Invalid file format. We are only accepting image file. Pls. try again.<br></span>"; echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>"; } ?> So what the code suppose to do is.. If I upload an image file as the new logo it should have the default logo name "my_logo.gif", then it will overwrite the existing one... Anyone? Hi all, I have this script below where I am trying to display a default image if an image can not be found. For some reason though it is not working. <?php foreach (glob('./aircraft/' . $rowX['reg'] . '[0-8].jpg') as $file) { if (file_exists($file)) { echo "<img src=\"" . $file . "\" /><br />"; } else { echo "><img src=\"aircraft/wrightflyer.jpg\" /><br />";} } ?> Hi I have been trying to get a value to be selected in a mysql populated dropdown list but can't get it to work and was hoping someone could help I have a database with user info in it and this is an update page where they can update their details. The code i have (which doesn't work) is: <select name="agency"> <? $query1 = mysql_query("SELECT * FROM agents ORDER BY agent ASC",$connect); while($myrow = mysql_fetch_assoc($query1)){ $agent = $myrow['agent']; echo "<option"; if ($agent == $agency) { echo "selected='selected'"; } echo ">$agent</option>"; } ?> </select> The $agency value is the current agency which is stored in the users profile and the value does exist in the list which is being populated (also, i have define $agency further up in my code) so i don't know why the selected value won't display. No value is displayed in the dropdown list on the page - but the values are in the list if i remove the selected='selected' part of the code. Any help yould be greatly appreciated. Merry Christmas Andy In PHP when you post a form the default font is Times New Roman how do I changes the font to arial Hi guys, Before we go further, yes, I know I should use prepared statements. This is just a project that will probably never go live. If I do decide to go live, I will change to prepared statements. Anyways, I am populating a text box from the selection of an options dropdown and updating MySQL. This all works fine. However, what I want to do is have the newly inserted option display by default in the dropdown. Hope this makes sense. Here is the dropdown code with the select statement... <div class="row form-group"> <div class="col-6"> <div class="form-group"><label for="location" class=" form-control-label">location</label> <?php $sql = "SELECT location_name, location_phone FROM locations"; $result = $con->query($sql); ?> <select name="location" id="location" onchange="myFunction()" class="form-control"> <?php while($r = mysqli_fetch_row($result)) { echo "<option data-location_name='$r[1]' data-location_phone='$r[2]' value='$r[0]'> $r[0] </option>"; } ?> </select> <label>Phone</label><input type="text" class="form-control" name="location_phone" id="location_name" value = "<?php echo $row['location_phone']; ?>"/> I am grabbing the location name and phone number from locations. Then inserting them into tours. So after the form is submitted, I want the location name to stay in the dropdown. This is in the table "tours". How do I implement that in here? Thanks heaps. Hello, i know this is a very silly question but it bothers me to know the reasoning behind it. My application has a design where the functions are stored in functions.php and variables are stored in variables.php. There are some functions that have variables that i might change often and the reason i don't directly use them in the argument itself is so that in future if i have to change the default argument's value , then i wouldn't have to scroll through all the functions and look for it. I have a slippery memory i know i will be able to remember it better if i store custom global variables separately and custom global functions separately. I tried searching these forums for this but its giving me a message like "search daemon not found" or something like that.. Anyways , coming to the point, i know that PHP doesn't accept variables as default arguments but may i know the reasoning behind this? If i understand the reasoning behind this i know it will stick better in my head.So..why does a function not allow a variable as a default value? Or if anyone has a link to explaining this behaviour in PHP, i would appreciate it if you could pass it on! Thank you |
