I created a page for multiple rows submit data to mysql with php!
But, I need filter check the checkbox[] has been checked for submit current row data
In my demo,
If I checked the row2 and row3, I expected I will get id=2 & id=3
finally I get the id=1 & id=2
In the same situation, if I checked row3 only, I will get the id=1
I probably understand the principle, but I really can’t find a solution
<?php
$row = "";
if ($_POST) {
foreach ($_POST["checked"] as $key => $v) {
if (#$_POST['checked'][$key] == "on") {
$row[$key]['id'] = $_POST['id'][$key];
$row[$key]['other_value'] = $_POST['other_value'][$key];
}
}
}
print_r($row);
?>
<form action="" method="POST">
<p>
<input type="checkbox" name="checked[]">
<input type="text" name="id[]" value="1">
<input type="text" name="other_value[]" value="a">
</p>
<p>
<input type="checkbox" name="checked[]">
<input type="text" name="id[]" value="2">
<input type="text" name="other_value[]" value="b">
</p>
<p>
<input type="checkbox" name="checked[]">
<input type="text" name="id[]" value="3">
<input type="text" name="other_value[]" value="c">
</p>
<button type="submit">submit</button>
</form>
I try #CBroe
if checked row3, I still get a
<?php
$row = "";
if ($_POST) {
foreach ($_POST["checked"] as $key => $v) {
$row[$key]['checkbox'] = $_POST['checkbox'][$key];
$row[$key]['other_value'] = $_POST['other_value'][$key];
}
}
print_r($row);
?>
<form action="" method="POST" >
<p>
<input type="checkbox" name="checked[]" value="1">
<input type="text" name="other_value[]" value="a">
</p>
<p>
<input type="checkbox" name="checked[]" value="2">
<input type="text" name="other_value[]" value="b">
</p>
<p>
<input type="checkbox" name="checked[]" value="3">
<input type="text" name="other_value[]" value="c">
</p>
<button type="submit">Submit</button>
</form>

I'm trying to get a value of a form in Wordpress to PHP. The form is like this and it is displaying fine in the preview:
<form action=".../name.php" method="get">
<input type="checkbox" name="form_ques_4" value=0 />
<input type="checkbox" name="form_ques_4" value=1 />
<input type="checkbox" name="form_ques_4" value=2 />
<input type="submit" name="formSubmit" value="submit" />
</form>
If the user selected option 2, the value is 1 and this will later be used as the input in a MySQL database. As I have read in other posts, I should get value with the php line.
$a = $_GET["form_ques_4"];
I have tested some other simple outputs for the .php and there is no problem with the "form action" of the wordpress. I also tried using single and double quotes for the "GET" with no result.
Try to change the names of your checkboxes, if you want a user multiple choice:
<form action=".../name.php" method="get">
<input type="checkbox" name="form_ques_1" value="0" />
<input type="checkbox" name="form_ques_2" value="1" />
<input type="checkbox" name="form_ques_3" value="2" />
<input type="submit" name="formSubmit" value="submit" />
</form>
otherwise, if you want the user makes only one choice use type="radio"
<form action=".../name.php" method="get">
<input type="radio" name="form_ques_4" value="0" />
<input type="radio" name="form_ques_4" value="1" />
<input type="radio" name="form_ques_4" value="2" />
<input type="submit" name="formSubmit" value="submit" />
</form>
EDIT
yes, as AZinkey says, you can also use
<form action=".../name.php" method="get">
<input type="checkbox" name="form_ques[]" value="0" />
<input type="checkbox" name="form_ques[]" value="1" />
<input type="checkbox" name="form_ques[]" value="2" />
<input type="submit" name="formSubmit" value="submit" />
</form>
then get the results in php
$checked = $_GET['form_ques'];
for($i=0; $i < count($checked); $i++){
echo $checked[$i] . "<br/>";
}
Quote your value attribute like value="0" and update name to "form_ques_4[]"
<input type="checkbox" name="form_ques_4[]" value="0" />
I have some buttons in a first_page.php, and some checkboxes in a second_page.php.
I need to select the corresponding checkbox with a query string to get this:
When "first value button" is pressed --> "second_page.php" with "my first value" checkbox already selected.
first_page.php :
<form action="second_page.php">
<input class="btn" type="submit" value="first value button">
<input class="btn" type="submit" value="second value button">
<input class="btn" type="submit" value="third value button">
</form>
second_page.php :
<form name="name" method="post" action="#">
<input type="checkbox" name="mybox[]" value="my first value"/>
<span>my first box</span><br />
<input type="checkbox" name="mybox[]" value="my second value"/>
<span>my second box</span><br />
<input type="checkbox" name="mybox[]" value="my third value"/>
<span>my third box</span><br />
</form>
You have to specify a name for each input to connect it to $_POST then in second_page.php you have to fetch the form value.
In first_page.php:
<form action="second_page.php" method="post">
<input name="first_value_btn" class="btn" type="submit" value="first value button">
<input name="second_value_btn" class="btn" type="submit" value="second value button">
<input name="third_value_btn" class="btn" type="submit" value="third value button">
</form>
In second_page.php :
<input type="checkbox" name="prodotti[]" value="my first value" <?php echo ( isset($_POST['first_value_btn']) ? 'checked="checked"' : '');?> />

I've used POST as method in my example above, you could use GET instead and then replacing $_POST with $_GET instead.
I would give the Submit buttons names and then do a check on them on the next page:
<input type="checkbox" name="mybox[]" value="my first value" <?php if (isset($_POST['submit1'])) { echo 'checked'; ?> />
<input type="checkbox" name="mybox[]" value="my first value" <?php if (isset($_POST['submit2'])) { echo 'checked'; ?> />
<input type="checkbox" name="mybox[]" value="my first value" <?php if (isset($_POST['submit3'])) { echo 'checked'; ?> />
I'm using php. I'd like to know how can I test if a radio button is selected and get the value? i can test if the radio button is selected but i cannot get the value.
I created a button to test this in my form. First I select a radio button, then i click on the button and it must display a message that says which value i selected and put this value into a variable. In order to test if a radio button is selected i did like this:
$selected_radio=$_POST['SINGLE_' . $question->id . $multi_name_adjust . ''];
if ($selected_radio = 'checked'){}
Thanks
It's pretty simple, take a look at the code below:
The form:
<form action="result.php" method="post">
Answer 1 <input type="radio" name="ans" value="ans1" /><br />
Answer 2 <input type="radio" name="ans" value="ans2" /><br />
Answer 3 <input type="radio" name="ans" value="ans3" /><br />
Answer 4 <input type="radio" name="ans" value="ans4" /><br />
<input type="submit" value="submit" />
</form>
PHP code:
<?php
$answer = $_POST['ans'];
if ($answer == "ans1") {
echo 'Correct';
}
else {
echo 'Incorrect';
}
?>
A very more efficient way to do this in php:
<form action="#" method="post">
<select name="Color">
<option value="Red">Red</option>
<option value="Green">Green</option>
<option value="Blue">Blue</option>
<option value="Pink">Pink</option>
<option value="Yellow">Yellow</option>
</select>
<input type="submit" name="submit" value="Get Selected Values" />
</form>
<?php
if(isset($_POST['submit'])){
$selected_val = $_POST['Color']; // Storing Selected Value In Variable
echo "You have selected :" .$selected_val; // Displaying Selected Value
}
?>
and for check boxes multiple choice:
<form action="#" method="post">
<select name="Color[]" multiple> // Initializing Name With An Array
<option value="Red">Red</option>
<option value="Green">Green</option>
<option value="Blue">Blue</option>
<option value="Pink">Pink</option>
<option value="Yellow">Yellow</option>
</select>
<input type="submit" name="submit" value="Get Selected Values" />
</form>
<?php
if(isset($_POST['submit'])){
// As output of $_POST['Color'] is an array we have to use foreach Loop to display individual value
foreach ($_POST['Color'] as $select)
{
echo "You have selected :" .$select; // Displaying Selected Value
}
?>
Just simply use isset($_POST['radio']) so that whenever i click any of the radio button, the one that is clicked is set to the post.
<form method="post" action="sample.php">
select sex:
<input type="radio" name="radio" value="male">
<input type="radio" name="radio" value="female">
<input type="submit" value="submit">
</form>
<?php
if (isset($_POST['radio'])){
$Sex = $_POST['radio'];
}
?>
<?php
if (isset($_POST['submit']) and ! empty($_POST['submit'])) {
if (isset($_POST['radio'])) {
$radio_input = $_POST['radio'];
echo $radio_input;
}
} else {
}
?>
<form action="radio.php" method="post">
<input type="radio" name="radio" value="v1"/>
<input type="radio" name="radio" value="v2"/>
<input type="radio" name="radio" value="v3"/>
<input type="radio" name="radio" value="v4"/>
<input type="radio" name="radio" value="v5"/>
<input type= "submit" name="submit"value="submit"/>
</form>
take a look at this code
<form action="result.php" method="post">
Answer 1 <input type="radio" name="ans" value="ans1" /><br />
Answer 2 <input type="radio" name="ans" value="ans2" /><br />
Answer 3 <input type="radio" name="ans" value="ans3" /><br />
Answer 4 <input type="radio" name="ans" value="ans4" /><br />
<input type="submit" value="submit" />
</form>
php
<?php
if(isset($_POST['submit'])){
if(isset( $_POST['ans'])){
echo "This is the value you are selected".$_POST['ans'];
}
}
?>
I suggest you do it through the GET request:
for example, index.html:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<form action="result.php" method="post">
Answer 1 <input type="radio" name="ans" value="ans1" /><br />
Answer 2 <input type="radio" name="ans" value="ans2" /><br />
Answer 3 <input type="radio" name="ans" value="ans3" /><br />
Answer 4 <input type="radio" name="ans" value="ans4" /><br />
<input type="button" value="submit" onclick="sendPost()" />
</form>
<script type="text/javascript">
function sendPost(){
var value = $('input[name="ans"]:checked').val();
window.location.href = "sendpost.php?ans="+value;
};
</script>
this is sendpost.php:
<?php
if(isset($_GET["ans"]) AND !empty($_GET["ans"])){
echo $_GET["ans"];
}
?>
my form:
<form method="post" action="radio.php">
select your gender:
<input type="radio" name="radioGender" value="female">
<input type="radio" name="radioGender" value="male">
<input type="submit" name="btnSubmit" value="submit">
</form>
my php:
<?php
if (isset($_POST["btnSubmit"])) {
if (isset($_POST["radioGender"])) {
$answer = $_POST['radioGender'];
if ($answer == "female") {
echo "female";
} else {
echo "male";
}
}else{
echo "please select your gender";
}
}
?>
This is my HTML:
<form method="POST" action="">
<?php
$skillSubCategory = $skills->showSkills(24);
for ($i = 0; $i < count($skillSubCategory); $i++) {
?>
<input type="hidden" name="skillid" value="<?php echo $skillSubCategory[$i]['skill_id']; ?>" />
<?php echo $skillSubCategory[$i]['title']; ?>
<input type="submit" name="add" value="add" /><br />
<?php } ?>
</form>
<?php if (isset($_POST['add'])) {
echo $_POST['skillid'];
} ?>
Resulting source code:
<form method="POST" action="">
<input type="hidden" name="skillid" value="25" />
Animal Grooming
25
<input type="submit" name="add" value="add" /><br />
<input type="hidden" name="skillid" value="26" />
Dog Trainer
26
<input type="submit" name="add" value="add" /><br />
<input type="hidden" name="skillid" value="27" />
Dog Walking
27
<input type="submit" name="add" value="add" /><br />
<input type="hidden" name="skillid" value="28" />
Vet
28
<input type="submit" name="add" value="add" /><br />
<input type="hidden" name="skillid" value="29" />
Beekeeping
29
<input type="submit" name="add" value="add" /><br />
</form>
What it looks like:
I get number 29 for any button clicked. Any ideas what's wrong? Why the correct number wont show up when i click add?
You can also use the buttons themselves(without changing their values):
<input type="submit" name="skillid[25]" value="add" />
<input type="submit" name="skillid[26]" value="add" />
<input type="submit" name="skillid[27]" value="add" />
To retrieve the submitted value(its not the value in this case, its the first key of the posted array):
if(isset($_POST['skillid']) && is_array($_POST['skillid']))
{
echo key($_POST['skillid'])
}
Because when you have multiple fields with the same name attribute in a form, the last one always takes precedence (with the exception of submit buttons -- the one clicked will be the only one considered). So the last hidden input with the name skillid will always be sent to the server.
When using forms like this, you usually have to use separate forms for each button. Alternatively, change the value attribute of each button and consider that from your PHP code.
Change:
<form method="POST" action="">
to:
<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
then change the condition to:
if (isset($_POST['add']) && isset($_POST['skillid'])) {
EDIT: use the <option> tag instead
<select name="skillid">
<option value="25">Animal Grooming</option>
<option value="26">Dog Trainer</option>
...
</select>
Your PHP code now will be:
<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<?php
$skillSubCategory = $skills->showSkills(24);
<select name="skillid">
for ($i = 0; $i < count($skillSubCategory); $i++) { ?>
<option value="<?php echo $skillSubCategory[$i]['skill_id']; ?>"><?php echo $skillSubCategory[$i]['title']; ?></option>
<?php } ?>
</select>
<input type="submit" name="add" value="add" /><br />
</form>
if (isset($_POST['add']) && isset($_POST['skillid'])) {
echo $_POST['skillid'];
} ?>
