I have set up a form which has a tick box on it as well as a few textareas to enter comments. I want the user to have to complete the textarea(tutorComment) if they tick the tickbox(alert)
EDIT : Here is my complete code
if( !strlen($_POST['tutorComments']) && isset($_POST['alert'] )){
echo "<h3>You must enter a reason why you have clicked the alert box</h3>";
exit();}
This worked fine until I added this bit of code at the top of my php
if(isset($_REQUEST['submited']))
Can i not use the isset twice? I'm a bit confused as to why the code has stopped working
Thanks in advance

That's a lot of code, I can't say what exactly but some possible problems to look at:
looks like you're missing a '?>' at the top, on line before the DOCTYPE etc.
Form has no action="" so put the name of the current php file or $_SERVER['PHP_SELF']
student names option and alert input don't have closing tags
Try doing the isset on the submit button instead, no need for the hidden input:
if(isset($_REQUEST['submit'])) {or if(isset($_POST['submit'])) {
If it's still not working try moving that whole block of code to the top before outputting the form.
Instead of using empty() for this, just check that it's set or not:
if(isset($_POST['alert']))
$alert = $_POST['alert'];
else
$alert = "";
or for short: $alert = isset($_POST['alert'])?$_POST['alert']:"";
Instead of this:
if( !strlen($_POST['tutorComments'])
&& isset($_POST['alert'] )){
echo "You must enter a reason why you have clicked the alert box";
exit();
}
write it like this:
if(isset($_POST['alert'])){
if(!strlen($_POST['tutorComments']))
echo "You must enter a reason why you have clicked the alert box";
// leave out the exit()
}
or try different tests such as: if(strlen($_POST['tutorComments'])< 1) etc.

I am new to PHP coding. I have different preferences for the user to select from my html page. I want to retrieve all the check boxes selected by the user and display the hotel names which have all those preferences in them. For example if a user selects "Roof top", "Sea side" and "Swimming pool" check boxes, then the hotels against which their is a 1 placed in the respective columns in the mytrip.db database must be retrieved all at once and get displayed. My code takes only one checkbox value and displays the hotel name against that only. I want to display the hotels that contain all the preferences.
My code is below:

echo "<br/><b>Note :</b> <span>Similarily, You Can Also Perform CRUD Operations using These Selected Values.</span>";
}
else{
echo "<b>Please Select Atleast One Option.</b>";
}
}
?>
The problem with this code is that it only displays one checkbox value if I use query
SELECT hotel_name FROM Dubai WHERE $selected==1
I tried to save the check box values selected by making an array "prefarray". But when I execute the query that I have posted in my checkbox_value.php code it gives me error of "Undefined offset 3 in prefarray". I want the data base query to have only those checkbox values that have been selected by the user. For example if the user has selected 2 out of three checkboxes then my query should look like
SELECT hotel_name FROM Dubai WHERE $checkbox==1 AND $checkbox2==1;
Any help to achieve two of these tasks will be appreciated!
I have fixed and refactored (couldn't stop myself) your code.
I have changed column names to proper ones. There was some redundant code which did nothing so I got rid of it. The main thing you were looking for is concatenating each chosen column in foreach loop. I'm also checking selected values against hard coded $hotelOptions for protection against sql injection.
Here is what I got:
checkbox_value.php:
<?php
class MyDB extends SQLite3
{
function __construct()
{
$this->open('mytrip.db');
}
}
$db = new MyDB();
if(!$db){
echo $db->lastErrorMsg();
} else {
}
$hotelOptions = array('swimming_pool', 'roof_top', 'sea_side');
if (isset($_POST['submit'])) {
if (!empty($_POST['check_list']) && is_array($_POST['check_list'])) {
// Counting number of checked checkboxes.
$checked_count = count($_POST['check_list']);
echo "You have selected following ".$checked_count." option(s): <br/>";
// Loop to store and display values of individual checked checkbox.
$where = '';
foreach($_POST['check_list'] as $selected) {
echo "<p>".$selected ."</p>";
if (array_search($selected, $hotelOptions) !== false) {
$where .= " AND {$selected} = 1";
}
}
$where = substr($where, 5, strlen($where));
$sql = "SELECT hotel_name FROM Dubai WHERE {$where};";
$ret = $db->query($sql);
while($row = $ret->fetchArray(SQLITE3_ASSOC) ){
echo "<p> <br /></p>\n";
echo "\n". $row['hotel_name'] . "\n";
}
$db->close();
echo "<br/><b>Note :</b> <span>Similarily, You Can Also Perform CRUD Operations using These Selected Values.</span>";
} else {
echo "<b>Please Select Atleast One Option.</b>";

Now, i want to put button (link, whatever) next to each of the created user, and when i click on the button, new login form to be shown, after i fill all of the required fields and press on update button, the edited user to be shown in database.

This is code I use on my database 2 sets of code - view.php displays the records with an option to edit next to each record in the list then if you click on edit it opens edit.php displaying a form to change and save the details. If you need it I can send the table structure and contents as well. There is quite a lot of code but I want to give the whole picture of a working system that I think does exactly what you want. It is mysql but I am converting to mysqli

header("location:".SITE_URL."index.php?view=view_service");
}
}

I am doing PHP validations for my html values. However when PHP validation fails and I return back to the page, the select tag form data is cleared. Is there anyway to do save and reload the form data in php
<?php
$qualific=$passingyear="";
$qualificErr=$passingyearErr="";
if ($_SERVER['REQUEST_METHOD']== "POST") {
$valid = true;
//qualification validations starts here
if(empty($_POST["qualif"]))
{
$qualificErr="* Qualification is Required";
$valid=false;
}
else
{
$qualific=test_input($_POST["qualif"]);
}
//qualification validations starts here
/*yearOfPassing validation starts here*/
if(empty($_POST["yearpass"]))
{
$passingyearErr="* Year Of Pass is Required";
$valid=false;
}
else
{
$passingyear=test_input($_POST["yearpass"]);
}
/*yearOfPassing validation starts here*/
//if valid then redirect
if($valid){
include 'database.php';
echo '<META HTTP-EQUIV="Refresh" Content="0; URL=success.php">';
exit;
}
}
<form method="post" action="<?php htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<label>Qualification<span class="error">*</span>:</label>
<select name="qualif">
<option label="Select"></option>
<option>Below SSC(10 Std)</option>
<option>SSC(10 Std) passed</option>
<option>HSC(12 Std) passed</option>
<option>Graduate</option>
<option>Post Graduate</option>
</select>
<span class="error"><?php echo $qualificErr?></span> <br />
<br />
<label>Year of passing<span class="error">*</span>: </label>
<select name="yearpass">
<option label="Select"></option>
<option>1975</option>
<option>1976</option>
<option>1977</option>
</select>
</form>
try <?php if($_POST["qualif"] == "<value>") echo "selected"; ?> in each option tag.
like
<option <?php if($_POST["qualif"] == "Below SSC(10 Std)") echo "selected"; ?>>Below SSC(10 Std)</option>
Currently you are using <option> without values.
Use like :
<option value="SSC" <?php if(isset($_POST['qualif']) && $_POST['qualif'] == 'SSC') { echo "selected"; } ?> >SSC</option>
your are missing value parameter inside <option>.
you need to add some code inside <option> tag
Please try following code hope this will solve the issue.
<select name="qualif">
<option label="Select"></option>
<option value="Below SSC(10 Std)" <?php if($qualific == 'Below SSC(10 Std)') {?> selected <?php } ?>>Below SSC(10 Std)</option>
<option value=">SSC(10 Std) passed" <?php if($qualific == '>SSC(10 Std) passed') {?> selected <?php } ?>>SSC(10 Std) passed</option>
<option value="HSC(12 Std) passed" <?php if($qualific == 'HSC(12 Std) passed') {?> selected <?php } ?>>HSC(12 Std) passed</option>
<option value="Graduate" <?php if($qualific == 'Graduate') {?> selected <?php } ?>>Graduate</option>
<option value="Post Graduate" <?php if($qualific == 'Post Graduate') {?> selected <?php } ?>>Post Graduate</option>
</select>
<span class="error"><?php echo $qualificErr?></span> <br />
<br />
<label>Year of passing<span class="error">*</span>: </label>
<select name="yearpass">
<option label="Select"></option>
<option value="1975" <?php if($passingyear == '1975') {?> selected <?php } ?>>1975</option>
<option value="1976" <?php if($passingyear == '1976') {?> selected <?php } ?>>1976</option>
<option value="1977" <?php if($passingyear == '1977') {?> selected <?php } ?>>1977</option>
</select>
You should use jquery
<script type="text/javascript">
$(document).ready(function()
{
$("#id").val("<?php echo $_POST['qualif']; ?>");
});
</script>
I have created a form which has a number of fields which I am posting to a database.
At the bottom of the form I I have set some simply error checking to make sure all the required fields are complete.
When the user clicks the submit button my error checking take place and if there are errors it will output a string with the errors which it encountered.
These errors are currently displayed below the form but I want them to appear above the form fields. Is there anyway I can do this?
If I move the error checking code above the form field obviosly it does not work as it checks for errors before any of the field have been completed.
Any ideas how I can do this?
Here is the code
enter code here

There shouldn't be any problem having your error checking code "above" the form rendering code. Once the form has been submitted, presumably via POST, you have all of the form variables in an array (the $_POST array) and they can be used regardless of whether or not you decide to re-render the form or not.
You can make a hidden field in your form, for example
<input type="hidden" name="isSubmitted" value ="1">
Then, in your checking routines, you first check if $_POST['isSubmitted'] (or $_GET['isSubmitted']) == 1 If it's true, then you know that user have been submitted your form, and you can make your additional checks
