I'm trying to check a checkbox based on its database value, i have tried the following but no joy, any suggestions?
I am using Kohana framework.
public static function defaultdistance(){
$result = DB::select('value')->from('mytable')->where('key', '=', 'default-distance')->execute();
$distancestores = $result->as_array();
foreach($distancestores as $distancestore)
{
echo 'Value: '.$distancestore['value'];
}
}
<label class="shortLabel"><input type="radio" name="distance" value="10" <?php if ($distancestore['value'] == '10') echo "checked='checked'"; ?> /> 10 <?php echo $dict->transl('distance_km'); ?></label>
<label> </label><label class="shortLabel"><input type="radio" name="distance" value="15" <?php if ($distancestore['value'] == '15') echo "checked='checked'"; ?> /> 15 <?php echo $dict->transl('distance_km'); ?></label>
May be you need like this
$distancestores = $result->as_array();
foreach($distancestores as $distancestore)
{
?>
<label class="shortLabel">
<input type="radio" name="distance" value="10"
<?php if ($distancestore['value'] == '10') echo "checked='checked'"; ?> />
10 <?php echo $dict->transl('distance_km'); ?>
</label>
<?php
}
try this i think you have to use ternary operator to resolve this issue.
<input type="radio" name="distance" value="10"
<?php $select = $distancestore['value']=='10'?'checked':'';
echo $select; ?>
10 <?php echo $dict->transl('distance_km'); ?>

I have a table with 3 fields looking_id,user_id,looking. looking_id is unique.
$sql="SELECT looking_id,user_id,looking FROM `provider_service_need` WHERE `user_id`='$user_id'";
$stmt=$dbg->query($sql);
<input type="checkbox" name="What_services[]" id="What_services" value="person_care" <?php if($stmt=='person_care')echo checked;?> >
<input type="checkbox" name="What_services[]" id="What_services" value="child_care" <?php if($stmt=='child_care')echo checked;?> >
<input type="checkbox" name="What_services[]" id="What_services" value="pet_care" <?php if($stmt=='pet_care')echo checked;?> >
but it's not working.
Try this
$sql="SELECT looking_id,user_id,looking FROM `provider_service_need` WHERE `user_id`='$user_id'";
$stmt=mysql_query($sql);
while($result = mysql_fetch_array($stmt))
{
?>
<input type="checkbox" name="What_services[]" id="What_services_<?php echo $result['looking'];?>" value="person_care" <?php if($result['looking']=='person_care')echo "checked";?> >
<?php
} ?>
For pdo try this
$sql="SELECT looking_id,user_id,looking FROM `provider_service_need` WHERE `user_id`='$user_id'";
foreach ($stmt->query($sql) as $row)
{
?>
<input type="checkbox" name="What_services[]" id="What_services_<?php echo $row['looking'];?>" value="person_care" <?php if($row['looking']=='person_care')echo "checked";?> >
<?php
} ?>
in database values are stored as "A,B,C,D,E,F" etc.
now i have to fetch those data in the form for update.
i have to check the checkbox if it matches the value with database value.
i am doing this kind of code(which i know is wrong)
<input type="checkbox" name="time[]" value="free" <?php if(!strpos($row['best'], 'free')=="false") { echo "checked='checked'";} ?> />Free
<input type="checkbox" name="time[]" value="Open" <?php if(!strpos($row['best'], 'Open')=="false") { echo "checked='checked'"; }?>/>Open Source
<input type="checkbox" name="time[]" value="portable" <?php if(!strpos($row['best'], 'portable')=="false") { echo "checked='checked'"; } ?> />Portable
<input type="checkbox" name="time[]" value="support" <?php if(!strpos($row['best'], 'support')=="false") {
echo "checked='checked'"; }?> />Support
When strpos is 0 (first character), then it is equal to false if you use double = (==). You need to use ===false. Besides it should be false, not "false".
You can do in this way:
suppose you have four static values :
<
?php
$time = ['free', 'open' , 'portable', 'support']; // your checkboxes
$fromDb = explode(',', $row['best']);
foreach($time as $t):
?>
<input type="checkbox" name="time[]" value="<?php echo $t;?>" <?php if(in_array($t, $fromDb) { echo "checked='checked'";} ?> /><?php echo ucfirst($t);?>
<?php endforeach;?>
I'm drawing data from a MySQL database that dynamically places a question with 4-5 radio button choices for the answer. These radio buttons all belong to the same group, $quest_name. The first pass of the while statement will create 4 radio buttons belonging to radio group "question_1".
It creates 30-40 of these questions on a page, each with 4 radio buttons. I want the user to fill in all there answers and the page to post back to itself with the users answers still selected and then display if they were correct or not (functionality I still have to add).
I'm trying to follow http://www.w3schools.com/php/php_form_complete.asp as an example, but use a dynamically created radio button name instead.
This is what I have thus far:
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
<?php
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$quest_num = $row["id"];
$question = $row["question"];
$option_1 = $row["option_1"];
$option_2 = $row["option_2"];
$option_3 = $row["option_3"];
$option_4 = $row["option_4"];
$option_5 = $row["option_5"];
$answer = $row["answer"];
$quest_name = "question_" . $row["id"];
echo "(" . $quest_num . ") " . $question . "<br>";
?>
<label>
<input type="radio" name=<?php echo $quest_name ?>
<?php if (isset(echo $quest_name) && echo $quest_name == echo $option_1) echo "checked"; ?>
value=<?php echo $option_1 ?>><?php echo $option_1 ?>
</label>
<br>
<label>
<input type="radio" name=<?php echo $quest_name ?>
value=<?php echo $option_2 ?>><?php echo $option_2 ?>
</label>
<br>
<label>
<input type="radio" name=<?php echo $quest_name ?>
value=<?php echo $option_3 ?>><?php echo $option_3 ?>
</label>
<br>
<label>
<input type="radio" name=<?php echo $quest_name ?>
value=<?php echo $option_4 ?>><?php echo $option_4 ?>
</label>
<br>
<br>
<?php
}
} else {
echo "0 results";
}
$conn->close();
?>
<input type="submit">
</form>
The part causing me grief so far is:
<?php if (isset(echo $quest_name) && echo $quest_name == echo $option_1) echo "checked"; ?>
I have also tried:
<?php if (isset($quest_name) && $quest_name == $option_1) echo "checked"; ?>
and:
<?php echo (isset($quest_name) && $quest_name == $option_1) ? "checked" : ""; ?>
How do you post back to the same page what they've selected? Like in this case I'm trying to say if "question_1" is set and "question_1" is equal to "converter" (the first radio button option) then have it checked when submit button is clicked.
I'm not that good at web development, but I'm trying to create a website to help my fellow electrical technician classmates.
Thanks for any help.
EDIT :
Using this line of code fixed the issue:
<?php if(isset($_POST[$quest_name]) && $_POST[$quest_name]==$option_1) { echo 'checked="checked"'; } ?>
What you need is called Radio Group. In HTML layer it is created with same name for all and different values for each like this:
<p>
<label>
<input type="radio" name="RadioGroup1" value="Value1" id="RadioGroup1_0">
Radio</label>
<br>
<label>
<input type="radio" name="RadioGroup1" value="Value2" id="RadioGroup1_1">
Radio</label>
<br>
</p>
And when you want to get the user input in php layer you go like this:
<?php
//check if Radio Group 1 is set
if(isset($_POST['RadioGroup1'])) {
// print the value of Radio Group 1 choice
echo $_POST['RadioGroup1'];
}
?>
When you want to create a Selected Radio in HTML layer you go like this:
<input name="RadioGroup1" type="radio" id="RadioGroup1_1" value="radio" checked="checked">
So you have to check if user inputs the value of which radio like this:
<label>
<input type="radio" name="RadioGroup1" value="value1" id="RadioGroup1_0" <?php if(isset($_POST['RadioGroup1']) && $_POST['RadioGroup1']=='value1') { echo ' checked="checked"'; } ?>>
Radio</label>
<br>
<label>
<input type="radio" name="RadioGroup1" value="value2" id="RadioGroup1_1" <?php if(isset($_POST['RadioGroup1']) && $_POST['RadioGroup1']=='value2') { echo ' checked="checked"'; } ?> >
Radio</label>
You could use the following:
<input type="radio" name="<?php echo $quest_name ?>" value="<?php echo $option_1 ?>"
<?php if (isset($quest_name) && ($quest_name == $option_1)) echo "checked"; ?> />
I have this PHP/HTML Code that is selecting data from a MySQL Database:
<?php
$sql3="SELECT * from property_images where property_seq = '".$property["sequence"]."' ";
$rs3=mysql_query($sql3,$conn);
while($property_img=mysql_fetch_array($rs3))
{
?><tr>
<td colspan="2"><img src="http://domain.co.uk/img/property-images/<?php echo $property_img["image"]; ?>" width="80px" height="80px" /></td>
<td colspan="2"><input type="checkbox" name="image1" value="Y" <?php if($property_img["image1"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image2" value="Y" <?php if($property_img["image2"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image3" value="Y" <?php if($property_img["image3"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image4" value="Y" <?php if($property_img["image4"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image5" value="Y" <?php if($property_img["image5"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image6" value="Y" <?php if($property_img["image6"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image7" value="Y" <?php if($property_img["image7"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image8" value="Y" <?php if($property_img["image8"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image9" value="Y" <?php if($property_img["image9"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image10" value="Y" <?php if($property_img["image10"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image11" value="Y" <?php if($property_img["image11"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image12" value="Y" <?php if($property_img["image12"] == 'Y') { echo 'checked="checked"'; } ?> />
<input type="checkbox" name="image13" value="Y" <?php if($property_img["image13"] == 'Y') { echo 'checked="checked"'; } ?> /></td>
</tr><?php
}
?>
each row, has its own image with the columns image1 - image13
i want to update the table with the checkboxes that are checked and unchecked on the form update
how is this possible?
Thanks
If you mean that you want to update the $property_img["imagexx"] val on db depending on the user click on the checkbox you must use ajax.
Fire an event on triggering each checkbox and send the value to a php page that update the php.
Jquery Ajax function can help you on this task.
L
name all your checkboxes images[]
<input type="checkbox" name="images[]" value="1" />
<input type="checkbox" name="images[]" value="2" />
<input type="checkbox" name="images[]" value="3" />
<input type="checkbox" name="images[]" value="4" />
You can then update with PHP :
<?php
$q = "UPDATE property_images SET";
foreach($_POST["images"] as $image) {
$q .= " image" . $image ." = 'Y', ";
}
$q .= " property_seq = '".$property["sequence"]."' WHERE property_seq = '".$property["sequence"]."'";
mysql_query($q);
?>
First of all, mysql_ functions are deprecated, please google mysqli_ or PDO, mysql_ won't be supported on future versions, and is unsafe, etc
Your html output could be much simpler with a loop, also have an eye on putting the sequence number on a hidden field or something first:
<?php
$sql3="SELECT * from property_images where property_seq = '".$property["sequence"]."' ";
$rs3=mysql_query($sql3,$conn);
while($property_img=mysql_fetch_array($rs3)){
?>
<tr>
<td colspan="2"><img src="http://domain.co.uk/img/property-images/<?php echo $property_img["image"]; ?>" width="80px" height="80px" /></td>
<!-- THIS IS VERY IMPORTANT: send the sequence or ID through a hidden field, to know which row you are gonna update later-->
<input type="hidden" name="sequence" value="<?php echo $property_img['sequence']; ?>"/>
<td colspan="2">
<?php for($i = 1; $i <= 13; $i++): ?>
<input type="checkbox" name="images[]>" value="<?php echo $i; ?>" <?php if($property_img["image$i"] == 'Y') { echo 'checked="checked"'; } ?> />
<?php endfor ?>
</td>
</tr>
<?php
}
?>
Then this is the next page where the update is done, have a good look at the comments:
<?php
//Handle as you want the situation when there are no images selected instead of using an exit(), I used it here just for the quickness;
if(count($_POST['images'] < 1) exit('no images where selected to update');
$images = array();
for($i = 1; $i <= 13; $i++){
$string = "image$i = ";
if(in_array($i, $_POST['images'])){
$string .= "'Y'"; //notice the double quoting here, it's important
} else {
//This updates the table so if it was checked when loaded, but unchecked by the user, this makes the change!
$string .= "'N'";
}
}
//This creates a string like: image1 = 'Y', images2 = 'N', etc...
$images = implode(', ', $images );
//try to sanitize the query first ... I won't cos am just showing you your question xD
$sql = "UPDATE property_images SET $images WHERE property_seq = " . mysql_real_escape_string($_POST[sequence]) . ";
mysql_query($sql,$conn);
?>
I post values from check boxes into a database for a user profile. When the user goes to edit his/her profile I want the checkboxes that they selected previously to be checked so they don't lose that info after updating their profile. I have tried many different solutions but with no luck.
The check box values get entered into table name members_teachers into a column called focus and are seperated by a comma for example art,mathematics,dance etc I am not sure how close or far I am away at accomplishing my goal but I greatly appreicate any help or suggestions you can provide. Thank you very much in advance
My code to try and check the values is
<?php
$focusQuery = mysql_query("SELECT focus FROM members_teachers WHERE id = $member_id") or die;
while ($new_row = mysql_fetch_assoc($focusQuery)){
$focusRow = $row['focus'];
$focusValue = explode(',', $focusRow);
foreach($focusValue as $newFocus){
//echo $newFocus;
//echo "<br/>";
$result = mysql_query("SELECT focus FROM members_teachers WHERE focus LIKE '%$focusRow%'") or die;
if(mysql_num_rows($result) > $newFocus){
$checked = 'checked="checked"';
}
else{
$checked = '';
}
}
}
?>
This is my html
<label for="art-focus">Art</label>
<input name="focus[]" type="checkbox" value="Art" <?php echo $checked ?>>
<label for="math-focus">Mathematics</label>
<input name="focus[]" type="checkbox" value="Mathematics" <?php echo $checked ?>>
<label for="dance-focus">Dance</label>
<input name="focus[]" type="checkbox" value="Dance" <?php echo $checked ?>>
<?php
// Create connection
$con=mysqli_connect("hostname","username","pass","dbname");
// Check connection
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT focus FROM members_teachers WHERE id = $member_id");
while($row = mysqli_fetch_array($result))
{
$focus=explode(",",$row['focus']);
?>
<input type="checkbox" name="focus[]" value="Art" <?php if(in_array("Art",$focus)) { ?> checked="checked" <?php } ?> >
<input type="checkbox" name="focus[]" value="Mathematics" <?php if(in_array("Mathematics",$focus)) { ?> checked="checked" <?php } ?> >
<input type="checkbox" name="focus[]" value="Dance" <?php if(in_array("Dance",$focus)) { ?> checked="checked" <?php } ?> >
<?php
}
?>
<?php
$focusedValues = array();
$focusQuery = mysql_query("SELECT focus FROM members_teachers WHERE id = $member_id") or die;
while ($row = mysql_fetch_assoc($focusQuery)){
$focusedValues = explode(',', $row['focus']);
}
?>
<label for="art-focus">Art</label>
<input name="focus[]" type="checkbox" value="Art" <?php echo in_array('Art', $checked) ?>>
<label for="math-focus">Mathematics</label>
<input name="focus[]" type="checkbox" value="Mathematics" <?php echo in_array('Mathematics', $checked) ?>
<label for="dance-focus">Dance</label>
<input name="focus[]" type="checkbox" value="Dance" <?php echo in_array('Dance', $checked) ?>
I don't know why you were SELECTing for the second time, that's pointless, you already know what's checked because it's in $focusedValues. Also, in your code, $checked would be empty if nothing was checked and checked="checked" otherwise. You obviously need a variable for each input, no?
<?php $hobby = $row['hobbies'];
$hobbies = explode (' ', $hobby);
?>
<input type="checkbox" name="hobbies[]" value="cricket" <?php echo in_array('cricket', $hobbies?'checked':'') ?> >cricket
<input type="checkbox" name="hobbies[]" value="singing" <?php echo in_array('singing' , $hobbies ?'checked': '') ; ?> >singing
<input type="checkbox" name="hobbies[]" value="football" <?php echo in_array('football', $hobbies ?'checked': '') ; ?> >footballl
