I'm updating some countries values into db table. All countries fetch from TBL_COUNTRY table. Then few countries store to another table. I'm using implode function to store multiple values. it works fine. it stored like this in my db table Afghanistan,Argentina,Austria,Bangladesh.
I have tried this code
<?php
$exp_str = explode(',', $model_availability);
foreach($exp_str as $get_str)
{
echo $get_str;
}
?>
This above code return this output AfghanistanArgentinaAustriaBangladesh
How do I put tick on the checkbox based on this value?
<?php
$sql = "SELECT * FROM ".TBL_COUNTRY." ORDER BY country_name ASC";
$exe = mysql_query($sql, $CN);
while($r = mysql_fetch_array($exe))
{
?>
<input type="checkbox" name="model_availability[]" value="<?=$r['country_name']?>" id="<?=$r['country_name']?>" />
<label for="<?=$r['country_name']?>"><?=$r['country_name']?></label>
<?php } ?>
<input type="checkbox" name="model_availability[]" value="<?=$r['country_name']?>" id="<?=$r['country_name']?>"<?=(in_array($r['country_name'],$model_availability)?" checked":"")?> />
//In the input box just add a checked attribute, you will get.
" id="" checked = "true" />

Perhaps there may be an easier way to do this however, I need the project to select a patient from the drop down menu. Then when the dropdown menu has got a value, the text field needs to take the NHS number from that drop down menu (array) so that it can be posted elsewhere.
<select name="patient" class="textbox" required>
<option value="">Select a patient</option>
<?php
include 'dbconnection.php';
$sql = "SELECT * FROM clients ORDER by firstname ASC";
$result = mysqli_query($conn, $sql);
$result = $conn-> query($sql);
while($row=mysqli_fetch_array($result))
{
?>
<option value="<?php echo $row["firstname"]." ".$row["lastname"]; ?>">
<?php echo $row["firstname"]." ".$row["lastname"] .", ".$row["addressl1"].", ".$row["addressl2"].", ".$row["county"].", ".$row["postcode"].", ".$row["nhsnum"]; ?></option>
<?php
$nhs = $row['nhsnum'];
}
?>
</select>
<?php
$sql = "SELECT * FROM clients WHERE nhsnum = $nhs ";
$result = mysqli_query($conn, $sql);
$result = $conn-> query($sql);
while($row=mysqli_fetch_array($result))
{
?>
<input type="text" placeholder="NHS number" readonly value=" <?php echo $row["nhsnum"]; ?>">
<?php
}
?>
As you may see, I have created dummy variables of $nhs however its a static variable and doesnt change upon user selection from the drop down list. Can anyone explain how I can merge the two together.
DB setup
i think you should declare the $nhs outside the while loop
Use AJAX, as already suggested, or a form submit button. Your second query should be where your AJAX or submitted form goes. Use $_GET or $_POST, if you are using get or post method, to intercept the option value. Assign that value to your $nhs, then use as you have.
Set the option value to the $nhs value you want, not the person’s name. Example using $_POST
if(isset($_POST['patient'])){
$nhs=$_POST['patient'];
}else{
// whatever code you want to handle a non-submitted value.
}
Add additional code to prevent SQL injection.
In insert form I am using check boxes to insert values in database. Now, I want to get checked values in edit form so I can check new values or uncheck checked values.
First I get values from database (I am using pdo, I will not post connection code to db- it works):
get oprmea from database
$sql_oprema = "SELECT Oprema FROM dbo_emarketing_stavke_oprema WHERE Partner='$id'";
$n = $conn->query($sql_oprema);
while ($r = $n -> fetch()) {
$oprema_sql = $r['Oprema'];
}
I get values when I dump variables, output is not NULL.
I am using function to store values in database. Now I want to use same function for editing if posssible.
function emarketing_oprema(){
$link = new mysqli("localhost", "root", "le30mu09", "websoft");
$link->set_charset("utf8");
$sql=mysqli_query($link, "SELECT * FROM `dbo_emarketing_oprema` order by OpremaId asc ");
while($record = mysqli_fetch_array($sql)) {
echo '<input type="checkbox" name="oprema[]" value="'.$record['OpremaId']. '">' . $record['OpremaNaziv'] . ' <br/><br/> </input>';
}
}
I was wondering is it possible to use this function to get checked values checked.
use checked attribute
<input type="checkbox" checked>
or like this
<input type="checkbox" checked="checked">
You php will look like this:
while($record = mysqli_fetch_array($sql)) {
data='<input type="checkbox" name="oprema[]" value="'.$record["OpremaId"];
if(isset($record['checked'])) {//field in the database
data+=' checked="checked';
}
data+='">'. $record["OpremaNaziv"].'</br>';
}
I have an array of checkboxes.
<input type="checkbox" name="selection[]" value="move" />
<input type="checkbox" name="selection[]" value="move2" />
<input type="checkbox" name="selection[]" value="move3" />
<input type="checkbox" name="selection[]" value="move4" />
Depending on the number of checkboxes selected, a table with corresponding number of rows is generated.
for($x=0; $x<$N; $x++)
{
echo nl2br("<td><textarea name=art[] rows=10 cols=30></textarea> </td><td><textarea name=science[] rows=10 cols=30></textarea></td></textarea></td><td><textarea name=method[] rows=10 cols=30></textarea></td><td><textarea name=criteria[] rows=10 cols=30></textarea></td></tr>");
}
I cannot tell how many table rows with corresponding columns will be generated each time. So how to write the code to insert each set of row array is a problem. I have tried the
$optionsVal = implode(",", $data);
but that only works to store the selected options and not for the generated table rows and columns.Please can anyone help with this. Thanks in advance
Okay so I think I understand a little better, but perhaps you should relay your question in other terms.
Basically my understanding is that you are accepting an uncertain (within the boundaries of the number of checkboxes you have) number of checkboxes, which there in turn generate a row for each selected check box.
If you want to store these generated rows in mySQL you need to post the data back to the database
$result = mysqli_query($query, $conn);
$row = mysqli_fetch_array($result);
You need to set a $result similar to this, and store your check box values in it
In this example if the end-user hits the save button it inserts the values from the check box into a variable
if(isset($_POST["savebtn"]))
{
//inserting the new information
$id = $_POST[""];
$name = $_POST[""];
//iterate through each checkbox selected
foreach($_POST["checkbox"] as $loc_id)
{
$query = "INSERT INTO table(ID, Loc_Code) VALUES('$id', '$loc_id')";
$result = mysqli_query($query, $conn);
}
?>
This was just kinda taken from another example, but you are way off with the implode, you need to save the results of the php selection to variables first, and then assign them rows in mySQL by looping through the selection
UPDATE:
Okay, so you got them in an array, seelction[] - this is good now you would want to check to see if a certain value is selected...
if (in_array("move2", $_POST['selection'])) { /* move2 was selected */}
then you want to put that into a single string - you were right with the implode method
echo implode("\n", $_POST['selection']);
then echo it out with a foreach loop
foreach ($_POST['selection'] as $selection) {
echo "You selected: $selection <br>";
}
I have the following code:
<?php
$allform = $_POST['allform'];
parse_str($allform, $output);
$allquery = "SELECT * FROM wp_users";
$names = array();
$allresult = mysql_query($allquery) or die(mysql_error()); ?>
...
<?php
while ($rows = mysql_fetch_array($allresult)) {
$names[] = $rows['user_email'];
}
?>
The allform variable is a jQuery serialize string:
var allform = $('form#all').serialize();
Basically, I want to put the values from the form in the front end into a mysql select query in the back end.
The form is a bunch of checkboxes so the idea is that the SELECT something will have different number of values depending on what the user checks. Any ideas?
Thanks
The best thing to do could be something like this. Your checkboxes should be like this
<input type="checkbox" name="checkboxes[]" value="cream" />
<input type="checkbox" name="checkboxes[]" value="choco" />
<input type="checkbox" name="checkboxes[]" value="lime" />
server side you receive an array
$flavours = $_POST["checkboxes"];
$sql = "SELECT ".implode(',', $flavours)." FROM FLAVOURTABLE";
I have inserted some check box values in mysql database using PHP
And in the below image i have fetch the values:
Now i need the o/p like the below image: The values which i inserted in the database should be checked
Hope now its clear.
Thanks in advance..
You should have a table of available options (in this case, something like a cities table), and then a user-to-cities look-up table. Then you can loop over the cities, but also fetch which cities the user has checked.
A sample, without knowing your database structure, would be as follows:
$uid = $_SESSION['user']['id']; // your logged in user's ID
$cities = array();
// get an array of cities
$sql = "SELECT id, name FROM cities";
$res = mysql_query($sql);
while ($row = mysql_fetch_object($res)) {
$cities[$row->id] = $row->name;
}
// get an array of cities user has checked
$sql = "SELECT DISTINCT city_id FROM users_cities WHERE user_id = '$uid'";
$res = mysql_query($sql);
while ($row = mysql_fetch_object($res)) {
$checked[] = $row->city_id;
}
// this would be templated in a real world situation
foreach ($cities as $id => $name) {
$checked = "";
// check box if user has selected this city
if (in_array($checked, $id)) {
$checked = 'checked="checked" ';
}
echo '<input type="checkbox" name="city[]" value="'.$id.'" '.$checked.'/>';
}
If I understand you question properly, the obvious and simplest approach is that you need to fetch records from database and when producing HTML [in a loop ot something similar] check if that value exists in array to results. You haven't given us any examples of your DB structure or code, so you must figure it our yourself how to do it.
Usually, you insert the values into the database. After inserting, you should have access to the same values again. It's not clear how you set up your script, so let's assume you redirect to another script.
What you need to do is retrieve the values for the checkboxes from your database again. Then you know which are selected. This can be used to determine if your checkbox need to be checked or not.
Note:
I assume here that the result of your query is an array with
the selected Ids as a value.
I assume here that your fields are stored in the result of
some query and is basically an array
with Field Id as key and Field Name
as Value.
E.g., something like this:
<?php
// Retrieve values from database.
$resultArray = ... some code ... ;
?>
<?php foreach ($field_types as $field_name => $field_value): ?>
<input type="checkbox" name="<?php echo $field_name; ?>" value="<?php echo $field_value ?>" <?php if (in_array($field_name, $resultArray)) { echo 'checked'; }/>
<?php endforeach; ?>
This results in a checkbox which is checked, if the field_name is inside the result array (with your already checked results). Otherwise they're just rendered as unchecked checkboxes. Hope this is clear enough.
