PHP - Hierarchy Drop Down List Code Issues
Hello,
I'm not able to figure how to fix these warnings / errors I'm getting. The file that I'm creating comes out correctly so it's as if I need some type of conditional to end the function calls or something? I'm really stumped with this one... Code: [Select] Undefined index: 1 Invalid argument supplied for foreach() Undefined index: 4 Invalid argument supplied for foreach() Undefined index: 7 Invalid argument supplied for foreach() Undefined index: 21 Invalid argument supplied for foreach() Undefined index: 2 Invalid argument supplied for foreach() Undefined index: 11 Invalid argument supplied for foreach() Undefined index: 6 Invalid argument supplied for foreach() Undefined index: 22 Invalid argument supplied for foreach() Undefined index: 24 Invalid argument supplied for foreach() Here is a var_dump of $menu Code: [Select] array(2) { ["items"]=> array(12) { [1]=> object(stdClass)#17 (10) { ["id"]=> string(1) "1" ["name"]=> string(4) "HOME" ["parent"]=> string(1) "0" ["type"]=> string(9) "slideshow" ["order"]=> string(1) "1" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [5]=> object(stdClass)#18 (10) { ["id"]=> string(1) "5" ["name"]=> string(4) "INFO" ["parent"]=> string(1) "0" ["type"]=> string(6) "parent" ["order"]=> string(1) "2" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [3]=> object(stdClass)#19 (10) { ["id"]=> string(1) "3" ["name"]=> string(9) "GALLERIES" ["parent"]=> string(1) "0" ["type"]=> string(6) "parent" ["order"]=> string(1) "3" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [18]=> object(stdClass)#20 (10) { ["id"]=> string(2) "18" ["name"]=> string(16) "GALLERY SECTIONS" ["parent"]=> string(1) "0" ["type"]=> string(14) "gallery_portal" ["order"]=> string(1) "4" ["visible"]=> string(4) "true" ["image"]=> string(11) "DSC0250.jpg" ["color"]=> string(6) "848a5a" ["link"]=> NULL ["target"]=> NULL } [22]=> object(stdClass)#21 (10) { ["id"]=> string(2) "22" ["name"]=> string(7) "CONTACT" ["parent"]=> string(1) "0" ["type"]=> string(5) "forms" ["order"]=> string(1) "5" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [24]=> object(stdClass)#22 (10) { ["id"]=> string(2) "24" ["name"]=> string(12) "MAILING LIST" ["parent"]=> string(1) "0" ["type"]=> string(5) "forms" ["order"]=> string(1) "6" ["visible"]=> string(5) "false" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [2]=> object(stdClass)#23 (10) { ["id"]=> string(1) "2" ["name"]=> string(7) "WEDDING" ["parent"]=> string(1) "3" ["type"]=> string(7) "gallery" ["order"]=> string(1) "1" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [4]=> object(stdClass)#24 (10) { ["id"]=> string(1) "4" ["name"]=> string(8) "ABOUT US" ["parent"]=> string(1) "5" ["type"]=> string(9) "text_page" ["order"]=> string(1) "1" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [7]=> object(stdClass)#25 (10) { ["id"]=> string(1) "7" ["name"]=> string(8) "CALENDAR" ["parent"]=> string(1) "5" ["type"]=> string(8) "calendar" ["order"]=> string(1) "2" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [21]=> object(stdClass)#26 (10) { ["id"]=> string(2) "21" ["name"]=> string(14) "PORTFOLIOSITEZ" ["parent"]=> string(1) "5" ["type"]=> string(8) "external" ["order"]=> string(1) "3" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> string(25) "http://portfoliositez.com" ["target"]=> string(6) "_blank" } [11]=> object(stdClass)#27 (10) { ["id"]=> string(2) "11" ["name"]=> string(9) "LANDSCAPE" ["parent"]=> string(2) "18" ["type"]=> string(7) "gallery" ["order"]=> string(1) "1" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } [6]=> object(stdClass)#28 (10) { ["id"]=> string(1) "6" ["name"]=> string(9) "PORTRAITS" ["parent"]=> string(2) "18" ["type"]=> string(7) "gallery" ["order"]=> string(1) "2" ["visible"]=> string(4) "true" ["image"]=> NULL ["color"]=> NULL ["link"]=> NULL ["target"]=> NULL } } ["parents"]=> array(4) { [0]=> array(6) { [0]=> string(1) "1" [1]=> string(1) "5" [2]=> string(1) "3" [3]=> string(2) "18" [4]=> string(2) "22" [5]=> string(2) "24" } [3]=> array(1) { [0]=> string(1) "2" } [5]=> array(3) { [0]=> string(1) "4" [1]=> string(1) "7" [2]=> string(2) "21" } [18]=> array(2) { [0]=> string(2) "11" [1]=> string(1) "6" } } } And here is the code Code: [Select] public function sitemap() { $query = $this->db->order_by('parent', 'asc')->order_by('order', 'asc')->get('menu'); foreach($query->result() as $row) { $menu['items'][$row->id] = $row; $menu['parents'][$row->parent][] = $row->id; } function build_map($parent, $menu, &$data) { foreach($menu['parents'][$parent] as $itemId) { if(!isset($menu['parents'][$itemId])) { if(($menu['items'][$itemId]->parent == 0) && ($menu['items'][$itemId]->visible != 'false')) { $name = str_replace(' ','-', $menu['items'][$itemId]->name); $data .= "\t<url><loc>" . base_url() .

I have a pretty good understanding of what needs to be done, but actually implementing and accomplishing is difficult for me. Im trying to break down hierarchy from an existing HTML list. First Id like to point out that I am working with an HTML file that I must use, and cannot change, as the source. I am rewriting onto another file, removing HTML, and so forth. I have already accomplished this. But what I would really like to keep the hierarchy structure by breaking it down first, so I can also use that later. Example HTML list Code: [Select] <ul><li>modem, UP</li> <ul><li>wifiRouter, UP</li> <ul><li>PC1, DOWN</li> <ul></ul> <!-- Open-close of UL identifies end --> </ul> <!-- Up one level --> <ul><li>wiredRouter, UP</li> <ul><li>server, UP</li> <ul><li>dnsServer, UP</li> <ul></ul> <!-- Open-close of UL identifies end --> <ul><li>webServer, UP</li> <ul></ul> <!-- Open-close of UL identifies end --> </ul> <!-- Up one level --> <ul><li>PC2, UP</li> <ul></ul> <!-- Open-close of UL identifies end --> </ul> <!-- Up one level --> </ul> <!-- Up one level --> <ul><li>modemBackup, DOWN</li> <ul></ul> <!-- Open-close of UL identifies end --> </ul> Desired Output: Code: [Select] 1, 0, 0, 0, modem, UP 1, 1, 0, 0, wifiRouter, UP 1, 1, 1, 0, PC1, DOWN 1, 2, 0, 0, wiredModem, UP 1, 2, 1, 0, server, UP 1, 2, 1, 1, dnsServer, UP 1, 2, 1, 2, webServer, UP 1, 2, 2, 0, PC2, UP 2, 0, 0, 0, modemBackup, DOWN If im logically looking at this right (1) Count <ul> entry and continue counting for each group (2) Stop group count at end argument <ul></ul> (3) The immediate next end argument </ul>, following (2), says to continue counting the previous group +1 (4) Repeat steps 1-3 until end Any advise? I have a search function in php where the text characters are matched to characters in a tables field--- works perfectly.... I need to make the input box have a droplist of words from database, this is also easy for me to do. the problem here is there is no definitive value! the options list always outputs a blank in the url--- its supposed to search a matching value and then output the matching value to url... Here is the droplist code: $output['RATESTITLE']='<input class="inputbox" type="text" size="24px" name="ratestitle" value="'.$sch->filter['ratestitle'].'" onfocus="if (this.value ==\''.$output['LANGUAGE_SEARCH_RATESTITLE'].'\') {this.value = \'\'}" />'; this outputs a input text box--- i want to have a droplist of options to populate this text box... If you must know this is the third day im at it... having a problem importing a file having multiple hierarchy levels!! its a csv file the contents look something like this! just need a jump start! thanks the file looks likes this row 1 row2 row3 name1 subj1 abcd efgh subje2 test1 test2 the file has to first import name1 then subj1 then abcd,then efgh then move back to subj2 and so on! Thanks Hi guys, I'm trying to build an array to replicate the hierarchy in a menu: <ul> <li><a href="file1.html">text1</a></li> <ul> <li><a href="file2.html">text2</a></li> <li><a href="file3.html">text3</a></li> <li><a href="file4.html">text4</a></li> <li><a href="file5.html">text5</a></li> </ul> </ul> An i would like the output to be:
"text1" Here is my loop to go through the html hierarchy:
foreach ($html2->find('ul') as $ul) {
foreach ($ul->find('li') as $li) {
foreach($li->find('a') as $a) {
// need to filter out empty and index.html, tried if(!$->href = 'index.html) {do stuff} but didn't work
$links2[] = $a->href ;
$taxo2[] = $a->plaintext ;
}
}
}
This finds all the links but not the hierarchy, any ideas how to approach this? And also how to filter out blanks and references to index.html? I have a "select"-drop down bar and I want to have a numbered list in it, i've tried but it doesn't seem to be possible. Is there any way that i'm able to do this? Helllo Every1 well im kinda new to php and i needed some help i was working on a page all my text boxes and check boxes are at the bottom of my file and like this //====================================================================== </script> </head> <body> <div style="margin-left: 170px"> <input type="checkbox" id="getitems" checked value="1">Run Plugin? <input type="checkbox" id="sellitm" checked value="1">Sell Items?<br><br> Item Name:<br><input type="text" id="itemd" value=""><br><br>How Many Cycles?:<br><input type="text" id="runtm" value="10"></div> <div style="margin-left: 170px"><br> <button id="btn_save" style="color:white;background-color:#00660F;border-width:1px;border-style:solid; "> Save settings </button> </div> '; echo $this->ObjectTable(); echo ' </body> </html> '; } } ?> and well i decided to do away wit one of the text boxes and use a drop down list instead that is populate from a text file and the only code that i could find that i was able to get working was this 1 <?php $text = file_get_contents("itemlist.txt"); $array = explode("\n",$text); echo "<select>"; foreach ($array as $value) { echo "<option value='$value'>$value</option>"; } echo "</select>"; and the problem im having is with that one it just stays at the top of the page when loaded like i have no way to position it... and im really stuck i tried saving it in another php and i tried using <?php include(); ?> function but it did not work if any1 could help me out that would be awsome. T.I.A Hi ,
I am pretty new to php. I would like to create a php website based on folders.
I have a code so far that shows the names of folder in a selection box. What I would like to achieve now is how i get the images inside the folder after I click on submit. I know how to get the images with a glob function. What I don't know is how to get the value of each specific folder name. How would I do that?
I have this code so far to get the names of the folders in the selection box:
<form action="test.php" method="post">
<select name="myDirs">
<option value="" selected="selected">Select a genre</option>
<?php
$dirs = glob("*", GLOB_ONLYDIR);
foreach($dirs as $val){
echo '<option value="'.$val.'">'.$val."</option>\n";
}
?>
</select>
<input type="submit" name="submit2">
<?php
if (isset($_POST['submit2']))Basically I have a form and What I want it to do is when a user selects the 'For Sale' radio button the minimum and maximum prices will be displayed in the drop down list as "70,000"+ but when the user selects the 'To Rent' radial button then the minimum and maximum drop down list prices will change to e.g. "200"+. How would I do this? Heres my Code for the form: Code: [Select] <div id="ptype"> <input type="radio" class="styled" name="ptype" value="forsale"/> For Sale <p class="increase"> <input type="radio" class="styled" name="ptype" value="forrent"/> To Rent </p> <p class="increase"> <input type="radio" class="styled" name="ptype" value="any"/> Any </p> </div> </td> </tr> </table> <div id="table2"> <table id="NBtable"> <tr> <td><p class="NBS">Number of bedrooms:</p></td> <td><div id="NB"> <select name="min bedrooms"> <?php $roomLimit = 5; for($minRooms = 0; $minRooms <= $roomLimit; $minRooms++){ if ($minRooms == 0){ echo"<option value=\"0\" selected=\"selected\">No Min</option>"; } else{ echo "<option value=\"$minRooms\">$minRooms</option>"; } } ?> </select> to <select name="max bedrooms"> <?php $roomLimit = 5; for($maxRooms = 0; $maxRooms <= $roomLimit; $maxRooms++){ if ($maxRooms == 0){ echo"<option value=\"0\" selected=\"selected\">No Max</option>"; } else{ echo "<option value=\"$maxRooms\">$maxRooms</option>"; } } ?> </select> </div> </td> <td><p class="PR">Price range:</p></td> <td><div id="PR"> <select name="min price" style='width:80px;'> <?php $priceLimit = 350; for($minPrice = 40; $minPrice <= $priceLimit; $minPrice =( $minPrice+ 10)){ if ($minPrice == 40){ echo"<option value=\"0\" selected=\"selected\">No Min</option>"; } else{ echo "<option value=\"$minPrice000\">£$minPrice,000</option>"; } } ?> </select> to <select name="max price" style='width:80px;'> <?php $priceLimit = 350; for($maxPrice = 40; $maxPrice <= $priceLimit; $maxPrice =( $maxPrice+ 10)){ if ($maxPrice == 40){ echo"<option value=\"0\" selected=\"selected\">No Max</option>"; } else{ echo "<option value=\"$maxPrice000\">£$maxPrice,000</option>"; } } ?> </select> Thanks in advance.

I have two basic dropdown lists in a form, my question is this: After selecting an item from the 1st dropdown list, the second dropdown list should automatically load only fields that are connected with the first selected item. (ex Site1 has Tank01 and Tank06, but Site2 has Tank03, Tank04 and also a Tank06). What is the script needed / or how do I change my script to accommodate this? Here is the basic script I use for the second dropdown list: <?php include("../xxx.php"); $cxn = mysqli_connect($host,$user,$password,$dbname); $query = "SELECT DISTINCT `diesel_tank_id` FROM `diesel_tank` ORDER BY `diesel_tank_id`"; $result = mysqli_query($cxn,$query); while($row = mysqli_fetch_assoc($result)) { extract($row); echo "<option value='$diesel_tank_id'>$diesel_tank_id</option>\n"; } ?> Hello all,
I am new in php and would like to help me in in code.
I would like to implement a html form that will upload to my linux server some files, some info as well and will run a bash command.
To be more clear, users will:
Send to the linux server two files (I have done it).
Select from a drop down list a specific directory, and once this specific directory has been selected to activate one other drop down menu with its childs.
Send all those info to a bash script.
For case b, assume that we have the following structure
my_dir/cars/brand1
my_dir/cars/brand2
my_dir/cars/brand3
my_dir/motors/brand5
my_dir/motors/brand6
the first drop down list should list only cars and motors while the second only brand1, brand2, and brand3 if cars is selected or brand5 and brand6 if motors is selected.
For case c, once the form is submitted, I would like the command:
./script.sh –a uploadedfile1 –b uploadedfile2 –c dropdown1 –d dropdpwn2
Any help is appreciated.
Best,
Hello, I'm trying to get a drop down list (ordinary html function, select option ...) but I want it to start from an image. When you click the image I want the drop down list to appear. Hove can I do this? /Pelle I have a drop down list which retrieves site name acronym and the url from the database. I need help in 2 things. 1.I do not want the url to be displayed in the drop down list. 2. When I hit submit I need to echo the sitename acronym as well as the url in a page called display.php. Here is my code so far: Code: [Select] <form action="display.php" method ="post"> <tr> <td>Category</td> <td> <select name="new_id"> <option value="">=============</option> <?php foreach($acronym as $key=>$value){ ?> <option value="<?php echo $value['site_id']; ?>"><?php echo $value['acronym']; ?></option> <option value="<?php echo $value['site_id']; ?>"><?php echo $value['url']; ?></option> <?php }?> </td> </tr> <input type="submit" name="submit" value="submit" /> </form> I'm doing this activity where a user chooses a base timezone and when the user clicks convert the current time in the selected GMT will be converted to GMT-11 to GMT+13. As of now, I have these codes: act09_view.php: Code: [Select] <?php session_start(); $s="GMT "; echo "Select the base time zone:</br>"; for($n=-11;$n<=13;$n++) { if ($n>=0) $s="GMT +"; $gmt[]=$s . $n . "</br>"; } echo "<select name='gmt'>"; foreach ($gmt as $value) { echo '<option value="' . $value . '">' . $value . '</option>\n'; } echo '</select>'; //$_SESSION['value']=$value; ?> <form action="act09_process.php"> </br><input type='submit' value='Convert'/> </form> act09_process.php: Code: [Select] <?php session_start(); //$value=$_SESSION['value']; //echo $value; date_default_timezone_set('Asia/Manila'); $gmttime=date('M j, Y g:i:s A'); echo "The current date and time at" . " is " . $gmttime; ?> I've tried using session variables. I think I executed them incorrectly. The output is supposed to look like this: I'm useing a simple HTML drop-down list box. But now I want to be able to and an editable drop-down box so that if the particular item in the drop-down is not changed it won't update the database. But if a new value is selected it will update the DB with the new value.
I am not clear on a couple of things. should the valuse of the drop down be in a seperate DB table. And then the script to change the new value or keep the old.
I've googled this and can't seem to find a workable solution.
Thanks in advance,
I'm using a CRUD system which won't automatically update the lft and rght values of my hierarchical tables when I enter a new row. I don't know what the best way to solve this is, all I can think of is adding a stored procedure to the table so that whenever a new row gets added, the procedure will make sure the lft and rght values get shifted. Is this even possible with stored procedures?
