We are using the Exec-PHP to use PHP in our wordpress page. But we got a problem, we cant read from a textfield form. Is this a Exec-PHP limmitation (If so could anyone recommend a plugin who does allow this) Or is something wrong in our code?
This is our code:
<form action="" method="post">
<input type="text" value="voornaam" />
<input type="submit" value="Verzend" />
<input type="hidden" name="button_pressed" value="1" />
<?php
if(isset($_POST['button_pressed']))
{
echo $_POST["voornaam"];
echo 'Done';
}
?>
You should add:
<input type="text" value="voornaam" />
Then, in your PHP, you can use:
echo $_POST["voornaam"];
Your form:
<form action="" method="post">
<input type="text" value="voornaam" />
<input type="submit" value="Verzend" />
<input type="hidden" name="button_pressed" value="1" />
</form>

I am trying to create a button, which downloads a file, and this file is created based on php variables.
The "instruction" to show this html code is inside a php file.
So far, I've got this ( don´t think it's ok ):
Inside the php this generates an email:
$addressforics = get_valueFromStringUrl($_SERVER['HTTP_REFERER'], 'address');
ob_start();
<form method="post" action="/download-ics.php">
<input type="hidden" name="date_start" value="2017-1-16 9:00AM">
<input type="hidden" name="date_end" value="2017-1-16 10:00AM">
<input type="hidden" name="location" value=$addressforics>
<input type="hidden" name="description" value="This is my description">
<input type="hidden" name="summary" value="This is my summary">
<input type="hidden" name="url" value="http://example.com">
<input type="submit" value="Add to Calendar">
</form>
$my_var = ob_get_clean();
How to insert the php variable $addressforics into the HTML code ( which is inside the same php code, where $addressforics is defined )?
You have to write the php code between <?php and ?>, as documented here.
Something like..
<?php
$addressforics = get_valueFromStringUrl($_SERVER['HTTP_REFERER'], 'address');
ob_start();
?>
<form method="post" action="/download-ics.php">
<input type="hidden" name="date_start" value="2017-1-16 9:00AM">
<input type="hidden" name="date_end" value="2017-1-16 10:00AM">
<input type="hidden" name="location" value="<?php echo $addressforics; ?>">
<input type="hidden" name="description" value="This is my description">
<input type="hidden" name="summary" value="This is my summary">
<input type="hidden" name="url" value="http://example.com">
<input type="submit" value="Add to Calendar">
</form>
<?php
$my_var = ob_get_clean();
?>
to write php value into html element
<input name="test" value="<?php echo $a ; ?> ">
or
<?php echo "<input name='test' value='".$a."'>"; ?>
I tried all but no form is working with method or simple action like http://google.com `
<form action="http://google.com" method="post">
<input type="text" />
<input type="submit" />
</form>
even this is not working
use this
<form role="form" action="http://google.com" method="post">
<input type="text" name="text" />
<input type="submit" name="submit" />
</form>
role attribute for FORM
name attribute for input
In PHP, $_POST always accept name attribute from form elements:-
You need to write
<input type="text" name='name_of_your_field' />
instead of
<input type="text" />
You need to refer this Link.
In this page : page.php?id=value
I've this html's code:
<form action="" method="get">
<input type="text" name="key" />
<input type="submit" name="send />
</form>
It's redirect me to: page.php?key=value , i want to redirect to: page.php?id=value&key=value , how i can do it? I must redirect it to this page with PHP ?
simply,
<form action="page.php" method="get">
<input type="hidden" name="id" value="<?php echo $value ?>">
<input type="text" name="key" />
<input type="submit" name="send" />
</form>
You can have the id as a hidden input in your form
<form action="" method="get">
<input type="hidden" value="<?php echo $my_id; /*Suppose this variable contain your value */ ?>" name="id" />
<input type="text" name="key" />
<input type="submit" name="send" />
</form>
put everything you want on the next page in your form:
<form action="page.php" method="get">
<input type="text" name="id" value="<?php echo $_REQUEST['id'];?>" />
<input type="text" name="key" />
<input type="submit" name="send />
</form>
Really though, you should be using POST to send data, and the above code is NOT secure (allows anything in a url to easily end up in a form that could create some sql injection or XSS type issues.
You need to have the form's action set to the page you want it to submit to. If it is blank it will just submit to the same page.
<form action="page.php?id=value&key=value" method="get">
<input type="text" name="key" />
<input type="submit" name="send />
</form>
I have multiple forms and I have one php script that I want to use to process these forms but when I click on submit for any of the forms...the script is processed by the number of forms with the submit button named 'submitForm' in this case, the alert will show 3 times instead of once! What am I not doing right?
NB. I hope this makes much sense?
html code
<form action="" name="form1" method="post">
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="Submit" value="Submit Form" name="submitForm" />
</form>
<form action="" name="form2" method="post">
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="Submit" value="Submit Form" name="submitForm" />
</form>
<form action="" name="form3" method="post">
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="Submit" value="Submit Form" name="submitForm" />
</form>
php script
<?php
if (isset($_POST['submitForm'])) {
echo('<script>alert("Form Submitted")</script>');
}
?>
when I click on submit for any particular form, it submits all the forms.
this is not true.
Once your forms have proper formatting, your browser will submit only current one.
(and PHP has nothing to do here)
however, whole page will be reloaded, if you mean that. That is okay - when you submit a form, a page is intended to reload. If you need another behavior, you have to explain your wishes.
Also note that none of your text fields being sent to the server as they have no names.
I guess the question I should be asking is, how do I pass a particular form to php instead of writing multiple php scripts to handle each form!!!
well, it seems you want to ask how to distinguish these forms.
add a hidden field into each
<input type="hidden" name="step" value="1" />
and then in PHP
if ($_POST['step'] == 1) {
//first form
}
if ($_POST['step'] == 2) {
//second
}
This submits one form of many to php. Copy, paste, test, and study.
<?php
if (isset($_POST['submitForm'])) {
print_r($_POST);
}
?>
<form action="" name="form1" method="post">
<input type="text" value="" name="A" />
<input type="text" value="" name="B" />
<input type="text" value="" name="C" />
<input type="text" value="" name="D" />
<input type="Submit" value="Submit Form" name="submitForm" />
</form>
<form action="" name="form2" method="post">
<input type="text" value="" name="A" />
<input type="text" value="" name="B" />
<input type="text" value="" name="C" />
<input type="text" value="" name="D" />
<input type="Submit" value="Submit Form" name="submitForm" />
</form>
<form action="" name="form3" method="post">
<input type="text" value="" name="A" />
<input type="text" value="" name="B" />
<input type="text" value="" name="C" />
<input type="text" value="" name="D" />
<input type="Submit" value="Submit Form" name="submitForm" />
</form>
Using a,b,c,d for the first form, e,f,g,h for the second form and i,j,k,l for the third form and submitting the second form yields the following output:
Array
(
[A] => e
[B] => f
[C] => g
[D] => h
[submitForm] => Submit Form
)

Actually its not hard.
Once you supply form names, your work is done. the DOM does the rest.
write one php block to do your functions (create/update/retrieve/delete)
Whichever button is clicked, by default it submits only the elements enclosed together with it.
if(!empty($_POST)){
if(isset($_POST['submit'])){
print "<pre>";
var_dump($_POST); // write your code here as you would
print "<pre>";
}
}
try this with your form above.
I know this is an old post but here's how I solve this very problem.
All you need to do is make sure the submit buttons in each form have different names. Eg:
<form action="" name="form1" method="post">
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="Submit" value="Submit Form" name="submitForm1" />
</form>
<form action="" name="form2" method="post">
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="Submit" value="Submit Form" name="submitForm2" />
</form>
<form action="" name="form3" method="post">
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="text" value="" />
<input type="Submit" value="Submit Form" name="submitForm3" />
</form>
Then, you simply check which form's submit button was pressed.
<?php
if (isset($_POST['submitForm1'])) {
echo('<script>alert("Form 1 Submitted")</script>');
} elseif (isset($_POST['submitForm2'])) {
echo('<script>alert("Form 2 Submitted")</script>');
} elseif (isset($_POST['submitForm3'])) {
echo('<script>alert("Form 3 Submitted")</script>');
}
?>
If you need dynamic forms, you may try below code. While statement can be changed to fetch data from DB and use foreach instead. Hope you know this.
Here, I used while($n<10) for 10 dynamic forms.
You can also use tag as below if you need separate form names.
<form action="" name="form<?=$n?>" method="post">
This will create separate form names such as form1, form2, etc but not necessary here.
<?php
if (isset($_POST['submitForm'])) {
echo '<pre>';
print_r($_POST);
echo '</pre>';
}
$n=0;
while($n<10) {
$n++;
?>
<form action="" name="form1" method="post">
<input type="text" value="" name="A" />
<input type="text" value="" name="B" />
<input type="text" value="" name="C" />
<input type="text" value="" name="D" />
<input type="Submit" value="Submit Form" name="submitForm" />
</form>
<?php
}
?>
Sample page with output when I click row 5..
I have several html textareas on my site. Each has a submit button. When a user types in one of the textareas i need to know which textarea this is. These textareas are each assigned a number taken from a mysql database. I can get the numbers out of the database, but how can I make it so that when a user types in a textarea and clicks submit the submit form knows which textarea this is. Please ask to clarify if needed. I tried my best to explain the problem. thanks.
p.s. the submit button just performs a mysql set values query. I'm using php on my site.
for example: a textarea is assigned '3.' When i submit this form i need 3 to be sent into my mysql set values query.
Use a hidden input to store a reference for each form
<input type="hidden" name="database_reference" value="<?php echo $dbId; ?>" />
Then when you submit the form $_POST['database_reference'] gives you the database id.
<input type="hidden" value="5" name="which_one" />
so for example
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="1" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="2" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="3" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="4" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="5" name="which_one" />
<input type="button" />
</form>
UPDATE:
<?php
if ($_POST){
include("db_connection.php");
mysql_query("UPDATE table SET column = '".mysql_real_escape_string($_POST['text'])."' WHERE value = ".intval($_POST['value']));
echo "done";
}
?>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="1" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="2" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="3" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="4" name="which_one" />
<input type="button" />
</form>
<form method="post" action="">
<textearea name="text"></textarea>
<input type="hidden" value="5" name="which_one" />
<input type="button" />
</form>
Assuming you have multiple <form></form> tags set up, one for each <textarea>, I would just add a hidden input field in each form. For example:
<form>
<textarea />
<input type="hidden" value="1" />
<input type="submit" />
</form>
<form>
<textarea />
<input type="hidden" value="2" />
<input type="submit" />
</form>
You can flesh it out from there, but you get the idea.
