PHP - Multiple Checkbox Update Code Igniter

Which languages do I need to make this happen? And I am unsure of how to incorporate PHP within a javascript query and what jQuery functions I will need. 

I have been trying to setup a tasty igniter site but it seems i am having some real issues i go through the setup and the wizard says finalising site setup then i get a sql error on my screen

"SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '1.0.0'' COLLATE utf8mb4_unicode_ci' at line 1 (SQL: ALTER TABLE ti_extensions CHANGE version version VARCHAR(32) DEFAULT ''1.0.0'' COLLATE utf8mb4_unicode_ci)"

after googling this error the only info i can find is that the database collation has to be set to utf8mb4_unicode_ci so i have been into phpmyadmin and changed the collation to this setting but i still get this same error message and its getting frustrating can anyone throw me some help please and thanks in advance

Or something like that... I am not sure how to put this..

Anyway, I'll just get started with explaining my problem.

I have an admin-page in which you can delete the comments given on blogs, using checkboxes and clicking on a button with the value 'verwijderenSubmit'. The deletion part works just fine, nothing wrong.

However, I also want to be able to EDIT the comments with an other button called 'bewerkenSubmit', using the same checkboxes that I use for deletion.
Selecting the right CID (CommentID) is no problem, because that works the same as the deletion-part, but selecting the right textarea to update into the database is the problem...

I uploaded a file here with the whole code: http://dhost.info/ddfs/myproblem.html
I escaped the textarea within with square brackets, because otherwise the whole textarea would screw up..
I also added <!-- RELEVANT CODE --> to select the parts that I need to change.

Well, I hope you understand my problem and can help.

I am using a WordPress theme that uses some of its own functions besides WP functions.

Let me make clear from the start that when I say "Multiple Checkboxes" in the paragraphs below I am NOT talking about checkboxes that each hold a single value.  I am talking about one Checkbox field that allows multiple values to be selected and puts those values into an array with one Name value and stores the output in a string in a single mysql table field.

Right up front, what I need during the Edit Ad functions is the inbuilt function that will Delete the previous Array of values in any multiple checkbox when the ad is updated. Right now updating the ad works for every situation except NO values selected or for Unchecking all previously selected values in a Multiple Checkbox.  If I have, for example, 4 checkboxes selected and unselect all of them before submitting the edited ad it will return the last saved array of values but not an Empty array with no checkboxes selected.

This theme has a Form Builder with a Custom fields builder used by the admin to create forms for a classified ads website. According to which category of ad the Ad creation procedure will show different forms, with different fields.

I had to manually create the capability to generate multiple checkboxes...so that the different multiple checkboxes when selected and updated to the mysql table might hold a variety of values in a comma-delimited array. That works fine.

When the Ad is edited on its own page, (outside of the Wordpress admin dashboard) the problem is that if a user would uncheck all checkboxes in a particular multiple checkbox then the unselected state does not overwrite the previous array of values. What returns after editing is the previous selected values.

I have tried jquery functions but none of them are working the way I had hoped.

so one type of checkbox might have a hypothetical value like this  "name="cp_checkbox_help[]" and if three options are selected then on submit the value could be--- name="cp_checkbox_help[Sunday,Monday,Tuesday]"

I use implode and explode to store the array as comma separated and retrieve the array for editing or display.

I guess I need to create a Null or empty value as a default that only changes when selections are made.

But, since I use implode and explode to make the array "pretty" I don't know if simply specifying nothing will erase a whole array on update.

Here is some of the code used to see how I get what I get--

This displays the checkboxes that I create and name and fill with different values--


case 'checkbox':
 ?>
<?php 
$options = explode(',', $result->field_values);
 echo '<div id="checkboxes"><table width="100%" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <th colspan="2" scope="col">' . $result->field_label. '</th>
  </tr>';
$myvals= explode(',', $post_meta_val);
foreach ($options as $option) {
 {
 ?> 
              
              <tr>
    <td width="4%"><input style="display:inline-block; float:left;" type="<?php echo $result->field_type; ?>" name="<?php echo $result->field_name; ?>[]" class="checkbox<?php if($result->field_req) echo ' required'?>" id="<?php echo $field_label; ?>" value="<?php echo $option; ?>" <?php foreach ($myvals as $myval)
{ if (in_array($myval, array($option), true)) {echo 'checked="yes"';}}?>/></td>
    <td width="96%"style="vertical-align:top; text-indent: 7px; text-align: left;" ><?php echo $option . '</td>
  </tr> ' ?>   



<?php
             }     } echo '  </tr>
</table></div><div class="clr"></div>';
 break; 



Following is the main part of the code that updates the Ad form--



  // update the ad and return the ad id
    $post_id = wp_update_post($update_ad);



    if($post_id) {

        // now update all the custom fields
        foreach($_POST as $meta_key => $meta_value) {
            if (cp_str_starts_with($meta_key, 'cp_'))
if (cp_str_starts_with($meta_key, 'cp_checkbox_charley'))
$meta_value= implode(',', $_POST['cp_checkbox_charley']);
if (cp_str_starts_with($meta_key, 'cp_checkbox_help'))
$meta_value = implode(',', $_POST['cp_checkbox_help']);
if (cp_str_starts_with($meta_key, 'cp_checkbox_hello'))
$meta_value= implode(',', $_POST['cp_checkbox_hello']);
                //echo $meta_key . ' <--metakey <br/>' . $meta_value . ' <--metavalue<br/><br/>'; // for debugging
                update_post_meta($post_id, $meta_key, $meta_value);
        }

        $errmsg = '<div class="box-yellow"><b>' . __('Your ad has been successfully updated.','cp') . '</b> <a href="' . CP_DASHBOARD_URL . '">' . __('Return to my dashboard','cp') . '</a></div>';

    } else {
        // the ad wasn't updated so throw an error
        $errmsg = '<div class="box-red"><b>' . __('There was an error trying to update your ad.','cp') . '</b></div>';

    }

    return $errmsg;

}

Back on the Edit Ad page this is the Submit


                        <p class="submit center">
                            <input type="button" class="btn_orange" onclick="window.location.href='<?php echo CP_DASHBOARD_URL ?>'" value="<?php _e('Cancel', 'cp')?>" />&nbsp;&nbsp;
                            <input type="submit" class="btn_orange" value="<?php _e('Update Ad &raquo;','cp') ?>" name="submit" />

I have a feeling what I need is just a couple of lines to detect no posted values and then... but if one checkbox array has 6 values in it and another checkbox array has only 3 values, for example, do I need to count each specific checkbox for number of values and then overwrite or will one function completely delete the previous array and its commas?

I would really appreciate some expert assistance here!

Hi I just barely made it through sending form to email using php. now I have another problem with checkboxes. please help! whenever I select multiple checkbox options. the form only sends me the last check box option checked. not all checked options.

Hi all:

I start an application in PHP and SQL Server for a company car and I need some recommendations.

The application tracked him to the maintenance of the cars. On one side are the car brands (Ford, Chevrolet, etc.) with the relevant goods and associated services. A relationship many-to-many.

On the other hand, the executives (stage 1) enter the customer associated with their cars and the corresponding products and services. The customer goes to the mechanic who performs the action (step 2) and finally counter that the collection (step 3).

My main problem is how to link Client - Automobile - Services in the first form. Enter the name and telephone number after a multi-select will select the brand and asynchronously checkbox must be loaded in all services and check the corresponding to that mark.


I find it difficult to incorporate all the links on the form. Appreciate design recommendations database (customer table) and how to assemble the form. Maybe some of you made any similar application or know a reference.

Finally thank you in advance for the time can provide for review this post.

I have  a form that has a list of checboxes, each checkbox has multiple values. IE. Checkbox1 has Date 1 and Cost1. Checkbox2 has Date2 and cost2 and so on.

This is what I have in form.

echo "<input type=checkbox name=service_id[] value=".$id."><label>".$description."</label> Date:<input type=date name=date[] value=".date('Y-m-d').">Date:<input type=number name=cost[] value=".$cost."><br>";

When i run the for loop to insert the values into a table i have this.

foreach($_POST['service_id'] as $key => $value){
$cat1=$_POST['service_id'][$key];
$cat2=$_POST['date'][$key];
$cat3=$_POST['cost'][$key];}

The problem is that when I select certain boxes (ie, checkbox #2), it inserts Date1 and Cost1 but does use the correct service id (ie checkbox)
I am clearly not storing the values into the array correctly. Any thoughts?

Is is possible to give multiple values in a single checkbox?
i need to have a checkbox that holds multiple values.

Help Anyone..

Hi. I have a form with a selection of checkboxes. I am trying to use an array to store the results in a single column of a mysql database. The problem is, instead of the values, it just stores 'array'.

Each checkbox is like so:

<input name="previous_diseases[]" value="Tuberculosis"/>

Here is my code:

Code: [Select]
<?php
try{
$pdo_options[PDO::ATTR_ERRMODE] = PDO::ERRMODE_EXCEPTION;
$database = new PDO('mysql:host=localhost;dbname=db', 'username', 'password', $pdo_options);
 
$execution=$database->prepare('INSERT INTO form(title, forename, surname, address_1, address_2, address_city, address_county, address_country, address_postcode, email, previous_diseases, hear) VALUES(:title, :forename, :surname, :address_1, :address_2, :address_city, :address_county, :address_country, :address_postcode, :email, :previous_diseases, :hear)'); 
$execution->execute(array('title' => $_POST['title'],
         'forename' => $_POST['forename'],
 'surname' => $_POST['surname'],
         'address_1' => $_POST['address_1'],
 'address_2' => $_POST['address_2'],
 'address_city' => $_POST['address_city'],
 'address_county' => $_POST['address_county'],
 'address_country' => $_POST['address_country'],
 'address_postcode' => $_POST['address_postcode'],
 'email' => $_POST['email'],
 'previous_diseases' => $_POST['previous_diseases'],
     'hear' => $_POST['hear']));
Can anyone please show me what I need to change to get the values inserted into the database.

Thank you

What I have is a page with a list of cars, each with a checkbox next to them.

Code: [Select]
<?php
$sth = null; $count = 0;
$sth = $dbh->prepare("SELECT * FROM garage WHERE warehouse_id = ? ORDER BY car_name ASC");
$sth->execute(array($_POST['ware_id']));
echo "<table>";
echo "<tr>";
echo '<td>Choose Vehicles:</td>';
echo "</tr>";
echo "<tr>";
echo "<td>";

echo "<form action='warehouse_ship_3.php' method='POST'>";
while($row = $sth->fetch()){
echo "<input type='checkbox' name='cars' value='".$row['uci']."' /> ID: ".$row['uci'].", ".$row['car_year']." ".$row['car_name']."<br />";  
}
echo "<input type='hidden' name='ware_id' value='".$_POST['ware_id']."' />";
echo "<hr />";
echo '<div class="center"><input class="myButton" type="submit" name="submit" value="Next" /></div></form>';
echo "</td>";
echo "</tr>";
echo "</table>";

?>
That works fine. What I'm trying to do with this second page, is select all the car's info from a table called "garage" which stores data for all the cars (car name, year, etc) and display it. UCI stands for Unique car id, every car has a different id. It works when the user only selects one car on the previous page, but if they select two or more cars, only the car with the highest UCI number shows up. How would I work it to display info on every car that they selected?

Code: [Select]
<?php
  if(empty($_POST['cars']))
  {
    echo("You didn't select any cars.");
  }
  else
  {
$sth = $dbh->prepare("SELECT * FROM `garage` WHERE `uci` = ?");
$sth->execute(array($_POST['cars']));
while($cars = $sth->fetch()){

echo"
".$cars['uci'].", ".$cars['car_year']." ".$cars['car_name']."
";
}
  }
?>

After a few days of searching and running across a problem what is almost like mine on these forums (cant seem to find the link now) where the person was looking to search a database using checkboxes.

What I am trying to do is use a list of checkboxes (http://www.animeseason.com/anime-list/categories/) exactly like this link and search my table which has the genres as columns.

I am new to PHP and don't really have a starting point. I have taken a bunch of examples and came up with this.

My HTML form with a list of all my checkboxes.
Code: [Select]
<form method="post" ACTION = "php/do_search.php">

My PHP script that right now seems to do nothing.

Code: [Select]
<?php
//if we got something through $_POST
if (isset($_POST['cat_check'])) {
    $con = mysql_connect("localhost","USERNAME","PASSWORD") or die("Connection error");
mysql_select_db("DATABASENAME")or die("database doesn't exist");

// sanitize user input
$cleanData = array();
foreach($_POST['cat_check'] as $_comp) {
    //$cleanData = mysql_real_escape_query($_comp);
}

// Build query
  $compStr = implode("'), ('", $cleanData);
  $sql = "SELECT anime_name WHERE $_comp='1'";
  
}
?>
My database has a layout of "Name of show, (every genere listed above)".

Thanks for any help.

So first of all, I have a confession, I used Dreamweaver to take care of all my database work. Pheww. Now that I got that of my chest, I am having problems, not only with my lack of experience working with databases, but with my script also. I need to insert multiple checkbox values into my database into the same cell. So I have searched around and I thought I had found a fairly good approach, but with Dw's hodgepodge of overcomplicated mess, I am finding problems integrating it. The error I am getting post submission is "Warning: mysql_real_escape_string() expects parameter 1 to be string, array given in C:\wamp\www\gov\ballot.php on line 10
Column 'involvement' cannot be null" So if you would, could you debug my script and give me some instruction along to way so that I can learn a little something too? Here is my script:

<?php require_once('Connections/ballot.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

  mysql_select_db($database_ballot, $ballot);

Hi,

I am new to php and need help.
I am building a library system for an assignment.
I want to provide a functionality that registers (adds) all transactions to defferent databases.
I am stuck on how to add a selected row (selected by a checkbox) to the database and make sure that 2 users cannot update the same record at the same time.

Thanks for your help.

bellow is my code:
