PHP - Need Help With Dynamic Dropdown
Hi guys. I am having a hard time finding a solution for this, is it possible to get not the value of a dropdown (oh what's it called??? ) but what is in between of the <option> tag?like,
Code: [Select] <select name="catID"> <option value=$row['c_id']>$row['c_name']</option> and save it to the database??cuz I'm using a dynamic dropdown which bases the content of another dropdown by the id of the previous. And so, if i save it to the database, instead of for example "BSA" is saved, the id of "BSA" which is "1" is saved..any ideas guys? Similar TutorialsHi guys, I've got this php script which display the users of my database in a dynamic dropdown: <?php include "leadscript/connect_to_mysql.php"; $canvass_name=""; $sql = mysql_query("SELECT * FROM csj_canvasser"); $appointmentCount6 = mysql_num_rows($sql); // count the output amount if ($appointmentCount6 > 0) { while($row = mysql_fetch_array($sql)){ $c_employee = $row["c_employee"]; $canvass_name .='<option value="' . $c_employee . '">' . $c_employee . ' </option>'; } } ?> <form> <select name="c_employee"> <option value="">Select a person:</option> <?php echo $canvass_name; ?> </select> </form> I was wondering if there's a way I can write a code to GET value I select from the dynamic dropdown and use it to write a select query. Thank The rest of my coding works however this part does not and I'm trying to figure out why. I'm sure my syntax isn't right so I hope someone can correct my mistake. $contentpageID = $_GET['id']; $query = "SELECT contentpages.contentpage, contentpages.shortname, contentpages.contentcode, contentpages.linebreaks, contentpages.backlink, contentpages.showheading, contentpages.visible, contentpages.template_id FROM contentpages WHERE contentpages.id = '" . $contentpageID . "'"; <label for="template">Template</label> <select class="dropdown" name="template" id="template" title="Template"> <option value="0">- Select -</option> <?php $query = 'SELECT * FROM templates'; $result = mysql_query ( $query ); while ( $template_row = mysql_fetch_assoc ( $result ) ) { print "<option value=\"".$template_row['id']."\" "; if($template_row['id'] == $row['template_id']) { print " SELECTED"; } print ">".$template_row['templatename']."</option>\r"; } ?> </select> Hi everyone, I've read through the FAQs for Dynamic Dropdown Menus on this site, as well as others, and I can't figure out why my code won't work. I have two dropdown boxes that need to be populated with data from a mysql table; one menu for route types, and one for route numbers. When I choose the route from the 'Route' menu, the 'Number' menu automatically populates with all of the possible numbers, rather than only those that correspond with the route type. I can tell that the problem has something to do with the value of 'Route' not being recognized, but I don't know why. I'm a beginner when it comes to PHP, so any suggestions or help would be much appreciated! Thanks! The code is as follows: Code: [Select] <html> <body> <basefont face='calibri' color='#7E2217'> <?php // set variables $mileTable = $_GET['mileTable']; $routeType = isset($_POST['Roadtype'])? $_POST['Roadtype']: 0; include 'opendbMile.php'; include 'error.php'; // Connect to the MySQL DBMS if (!($connection = @ mysql_connect($hostName, $username, $password))) die("Could not connect"); if (!mysql_select_db($databaseName, $connection)) showerror( ); // Start a query... $query = "SELECT ID, Roadtype FROM Alabama GROUP BY Roadtype"; // execute the SQL statement $result = mysql_query($query, $connection) or die(mysql_error()); echo '<form name="mileform" method="post" action="MileQuery.php">'; echo '<p>Route: <select name="routeType" id="routeType" onchange="this.form.submit();"> <option value="0"'.($routeType == 0? ' SELECTED': '').'>Route</option>'; while($row = mysql_fetch_array($result)){ echo ' <option value="'.$row[0].'"'.(($routeType == $row[0])? ' SELECTED': '').'>'.$row[1].'</option>'; } echo ' </select> </p>'; // create the SQL statement $query2 = "SELECT ID, Roadnumber FROM Alabama GROUP BY Roadnumber"; if($mnucategory != 0){ // Filter road numbers $query2 .= " WHERE Roadtype='".$routeType."'"; } // execute the SQL statement $result2 = mysql_query($query2, $connection) or die(mysql_error()); echo '<p>Number: <select name="routeNumber" id="routeNumber" onchange="this.form.submit();"> <option value="0"'.($routeNumber == 0? ' SELECTED': '').'>Number</option>'; while($row2 = mysql_fetch_array($result2)){ echo ' <option value="', $row2[0].'"'.(($routeNumber == $row2[0])? ' SELECTED': '').'>'. $row2[1], '</option>'; } echo ' </select> </p>'; // Close the DBMS connection mysql_close($connection); ?> </form> </body> </html> I want make the following, (I have already a database with three tables (Countries, Timeline and Category)). 1: list of countries (drop down menu 1), Timeline of the countries history (drop down 2) and Category (drop down 3). 2: The selected values of the drop down menus must show take the information from the database. Can any one help me with the coding? Hi all, here's my code: Code: [Select] <?php foreach ($_SESSION['topping'] as $value) { echo "<tr><td width='30%'>Topping</td><td width='50%'>$value</td><td width='20%'><select name='notopping'>"; foreach ($_SESSION['cupcake'] as $number) { '<option name="notoppings[]" value="'.$number.'">".$number."</option>'; } echo "</select></td></tr>"; } ?> $_SESSION['cupcake'] is a value from either 6, 12, 24 or 36. What I want to do is put them into a drop down box (second foreach) as the value and the displayed value - counting up from 1 (so 1,2,3,4,5,6 or up to 12,24 etc). Also by creating this as an array, does this mean than for each topping (say Vanilla and Chocolate) the value dynamically created can be used on the next page by using $_POST['notoppings'] to display each type (two different numbers - one for Vanilla and one for Chocolate). Does that make sense? Thanks! Jason Hi, I am hoping someone can help me out with a slight issue I have with php and mySQL. I have an ajax-powered form with a select (dropdown) field populated through a php function. Based on the user-selected values in this field, data is displayed on the webpage; i.e. selected value 1 returns values x and y on the page. I am now trying to call additional data (value z) from a different table in the same database, and as before, use the selected values from the dropdown to display the data. For some reason, value z is not changing according to the user-selected value. This is my code: [The function to populate the select field] Code: [Select] function kfl_get_funds_names() { $result = array(); $result['CDF'] = 'Crosby Dragon Fund'; $result['CPF'] = 'Crosby Phoenix Fund'; $result['AMZPIF'] = 'AMZ Plus Income Fund'; $result['KASBIIF'] = 'KASB Islamic Income Opportunity'; $result['KASBCPGF'] = 'KASB Capital Protected Gold Fund'; $result['KASBLF'] = 'KASB Income Opportunity Fund'; $result['KASBCF'] = 'KASB Cash Fund'; $result['KASBBF'] = 'KASB Asset Allocation Fund'; $result['KASBSMF'] = 'KASB Stock Market Fund'; return $result; } [the code calling and using the function to interact with the database] Code: [Select] $funds_to_display = kfl_get_funds_names(); $current_symbol = key( $funds_to_display ); $current_nav_rates = kfl_get_latest_rates( $current_symbol ); [the code calling additional data, value z, from the database, and using the info in the select field to filter it] Code: [Select] $cutoff = kfl_cutoff( $current_symbol ); The display of each of these items is as follows: Code: [Select] <?php echo $current_nav_rates['nav_date']; ?> <?php echo $funds_to_display[$current_symbol]; ?> <?php echo $cutoff['cutoff']; ?> I can't get the $cutoff code to display the correct values. It picks up the first symbol to display and doesn't change with user selection. The code for the selection box, by the way: Code: [Select] <select id="dailynav-funds" autocomplete="off" name="dnf"> <?php foreach ($funds_to_display as $fund_symbol => $fund_name) { echo '<option'; if( $fund_symbol == $current_symbol ) { echo ' selected="selected"'; } echo ' value="' . $fund_symbol . '">'; echo $fund_name; echo '</option>'; } ?> </select> I've tried to get data using $_GET['dnf'] into the cutoff code, but that throws up parse errors. What am I doing wrong, and how can I resolve this issue? Thanks in advance! I have a form with dropdown list that is populated with values from Sql Server table. Now i would like to use this selected item in SQL query. The results of this query should be shown in label or text field. So when a user selects item from dropdown menu, results from SQL query are shown at the same time. I have two dropdown list at the moment in my form. First one gets all values from a column in table in SQL Server. And the second one should get a value from the same table based on a selection in first dropdown list.
When i load ajax.php i get 2 error mesages: This is my code so far. I have tried to do it with this Ajax script. But i can only get first dropdown to work. The second dropdown(sub_machinery) does not show values, when first dropdown item is selected. The second dropdown should show values from databse table with this query( *$machineryID* is first dropdown selected item): SELECT MachineID FROM T013 WHERE Machinery=".$machineryID. Index.php

Folks, I need help (Php code ) to generate a Dynamic Text on a Base Image. What i want to do is, to make this Image as header on my Site and to make this Header Specific to a Site, i want to Add the Domain Name on the Lower Left of the Image. Got the Idea? Here is the Image link: Quote http://img27.imageshack.us/i/shoppingheader1.jpg/ PHP Variable that holds the Domain name is: $domain All i need the Dynamic PHP Codes that i can put on all my sites to generate this Text on Image (Header) Dynamically... May Anyone Help me with this Please? Cheers Natasha T. Hi freaks, I'm new to php first of all. I'm dynamically binding a dropdownlist with mysql database . After the user selects an item from it , I want to match that item with another table so as to populate another database. The code I'm using to populate dropdown: Code: [Select] <?php $con = mysql_connect("localhost","root",""); if(!$con) { die ('Can not connect to : '.mysql_error()); } mysql_select_db("ims",$con); $result=mysql_query("select cat_id,cat_name from category"); echo "<select name=cat>"; while($nt=mysql_fetch_array($result)) { echo "<option value=$nt[cat_id]> $nt[cat_name] </option>"; } echo "</select>"; mysql_close($con); ?> Now after the user selects any one of the item , I want to bind another dropdown on the same page using such query like $result=mysql_query("select subcategory.sc_id,subactegory.sc_name from subcategory,category where subcategory.sc_id=$nt[cat_id]"); Please anyone tell me the logic and code to do it. Also tell me do I need an intermediate page to post the 1st dropdown value and then continue with 2nd dropdown. I couldn't figure out the concept anyhow. Help on this will be highly appreiable . (Tell me if I'm not clear with my question) Hi all I need to combine these two scripts: Firstly, the following decides which out of the following list is selected based on its value in the mySQL table: <select name="pack_choice"> <option value="Meters / Pack"<?php echo (($result['pack_choice']=="Meters / Pack") ? ' selected="selected"':'') ?>>Meters / Pack (m2)</option> <option value="m3"<?php echo (($result['pack_choice']=="m3") ? ' selected="selected"':'') ?>>Meters / Pack (m3)</option> <option value="Quantity"<?php echo (($result['pack_choice']=="Quantity") ? ' selected="selected"':'') ?>>Quantity</option> </select> Although this works OK, I need it also to show dynamic values like this: select name="category"> <?php $listCategories=mysql_query("SELECT * FROM `product_categories` ORDER BY id ASC"); while($categoryReturned=mysql_fetch_array($listCategories)) { echo "<option value=\"".$categoryReturned['name']."\">".$categoryReturned['name']."</option>"; } ?> </select> I'm not sure if this is possible? Many thanks for your help. Pete I am not a developer but I can modify code to work for me. The following code works on my test machine (Windows 10, IIS, PHP 7.4) but doesn't work on my website (cPanel, Some version of Linux, PHP 7.4). The two dropdowns are for State and City. You are supposed to be able to select the state and then select a city from that state then bring up a report for craft breweries in the city. When selecting State from the first dropdown, the page refreshes, the URL is correct with the reports.php?cat=<STATE> so $cat is being set, but the first dropdown no longer has the state selected and the second dropdown is populated with All cities and not just one ones from the selected state. Any ides why this is working fine on one machine and not the other? Selected code from reports.php
<?php
?>
/////// for second drop down list we will check if State is selected else we will display all the cities/////
echo "<form method=post action='brewerylistbycity.php'>";
}
////////// Starting of second drop downlist /////////
//// End Form /////
I'm trying to have it shows the data from my array as each option will have a value of the user's id and the text for the option will be their name. As of right now it only shows the last person. Code: [Select] <?php echo form_label('Recipient', 'recipient'); ?> <?php $data = array( 'name' => 'to', 'class' => 'required' ); <?php echo form_label('Recipient', 'recipient'); ?> <?php $data = array( 'name' => 'to', 'class' => 'required' ); $options = array(); foreach($users AS $user) { $options = array ( $user->user_id => $user->first_name.' '.$user->last_name ); } ?> <?php echo form_dropdown($data, $options); ?> I currently have a web page which the user selects the value from the drop menu. I then want that value to go into another form in the same page inside a hidden field. Which will then be submitted to the processing php. The second option is the user selects the drop menu then the processing php would have to grab the value without a submit button because I am using a save button on the same page in the other form. Any help Hi, I'm wondering how i would go about making a drop down menu in php to insert the option into users > Maint of my database, if anyone has any tutorials or examples it would be great, Thanks a lot. Hi all. I kinda need some from a more advanced PHP expert. I have a table that displays time slots that are available to be booked.

Hi, I have a dropdown box, and I want it so that if dropdownbox.value='selected:' then show error message. The checkbox is dynamically populated. Pleaee Advise, - stuart Hello! If you search Google, you'll notice the URL: http://www.google.com/webhp?hl=en#hl=en&source=hp&q=php+freaks&aq=f&aqi=g10&aql=&oq=&gs_rfai=CtdaTdtdRTNnPD5HuzASZtMWiCgAAAKoEBU_Q0ZT5&pbx=1&fp=19d754eee0b4f223 You can copy that URL anywhere you like... and the user will still see the same results. So basically the URL dynamically does an action, and accesses the database. How on do I make a URL like this? Meaning when you change the URL parameter values, it request a slightly different database query? Does that make sense? Similarly with NexTag.com: http://www.nextag.com/serv/main/buyer/ProductCompare.jsp?search=camera&page=0&node=500001&psort=%2FDigital-Cameras--zzcameraz500001zB6z5---html&zipcode=&cptitle=657166355&cptitle=656751324&cptitle=620051906&cptitle=705150048 That was a Dynamically made URL (I selected from check boxes which products to compare) and it makes that URL so anyone can see those products. Any ideas on how to do this? More examples on the URL: http://www.cars.com/go/compare/modelCompare.jsp?myids=9721,11439 (i select the cars, it generates that URL. Notice the IDs 9721,11439) Hi, I am trying to call the data from Mysql but I am getting an empty drop down list, this is the code: mysql: Code: [Select] create table years ( yearID integer auto_increment, year varchar(30), primary key (yearID) ); insert into years (yearID, year) values ('1', '2007-2008'); insert into years (yearID, year) values ('2', '2008-2009'); insert into years (yearID, year) values ('3', '2009-2010'); insert into years (yearID, year) values ('4', '2010-2011'); insert into years (yearID, year) values ('5', '2011-2012'); insert into years (yearID, year) values ('6', '2012-2013'); PHP: Code: [Select] <?php require_once('../Connections/connection.php'); ?> <?php $result = @mysql_query( "select yearID, year, from sss.years"); print "<p>Select a year:\n"; print "<select name=\"yearID\">\n"; while ($row = mysql_fetch_assoc($result)){ $yearID = $row[ 'yearID' ]; $year = $row[ 'year' ]; print "<option value=$yearID>$year\n"; } print "</select>\n"; print "</p>\n"; ?> Thank you! |
