在PHP中将值从一个表单传递到另一个重定向的表单

<form class="form-horizontal" enctype="multipart/form-data" method="post" action="store.php">
    <div class="form-group">
        <label class="col-sm-2 control-label">REGISTRATION DATE</label>
        <div class="col-sm-8">
            <input type="date" class="form-control1" name="reg_date" id="focusedinput" placeholder="Default Input">
        </div>
        <div class="col-sm-2">
            <p class="help-block">text!</p>
        </div>
    </div>
    <div class="form-group">
        <label class="col-sm-2 control-label">REGISTRATION No.</label>
        <div class="col-sm-8">
            <input type="text" class="form-control1" name="reg_no" id="focusedinput" placeholder="Default Input">
        </div>
        <div class="col-sm-2">
            <p class="help-block">text!</p>
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-8">
            <input type="SUBMIT" value="Next" class="form-control1">
        </div>
    </div>
</form>

Here, in this code there are more input types, I just skipped those. When I will press submit button this will take me to 'store.php' file where informations will be stored in database. And redirect me to another form and there are also some input type but I need a information like "reg_no" from the previous form in the current form. How can I get this?

NOTE : I am storing the inputs of first form in a database table. Then redirected to other form and the action of this form is another PHP file like 'store2.php' and it is also using to store informations to other table of database.

You said that you are already passing the information from your current form into a database. When rendering your second form, you could grab whatever value you need from your database, and then add a value attribute to your input.

So for example if you have a form that looks like this in your second form:

<input type="text" class="form-control1" name="reg_no" id="focusedinput" placeholder="Default Input">

You can add that class to Pre-Fill the form when the page loads. Lets say you want it to show "12345":

<input type="text" class="form-control1" name="reg_no" id="focusedinput" placeholder="Default Input" value="12345">

I don't know the details of exactly how you are serving your site through PHP, but you could use some kind of string placeholder, or templating engine to put in this attribute.

Maybe this can help you :

this called form.php :

<form class="form-horizontal" enctype="multipart/form-data" method="POST" action="form_p.php">
  <div class="form-group">
    <label class="col-sm-2 control-label">REGISTRATION DATE</label>
    <div class="col-sm-8">
      <input type="date" class="form-control1" name="reg_date" id="focusedinput" placeholder="Default Input">
    </div>
    <div class="col-sm-2">
      <p class="help-block">text!</p>
    </div>
  </div>
  <div class="form-group">
    <label class="col-sm-2 control-label">REGISTRATION No.</label>
    <div class="col-sm-8">
      <input type="text" class="form-control1" name="reg_no" id="focusedinput" placeholder="Default Input">
    </div>
    <div class="col-sm-2">
      <p class="help-block">text!</p>
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-8">
      <input name="submit" type="SUBMIT" value="Next" class="form-control1">
    </div>
  </div>
</form>

this process of form.php, called form_p.php :

<?php
$reg_date = $_POST['reg_date'];
$reg_no = $_POST['reg_no'];
$submit = $_POST['submit'];

if (isset($submit)) {
    $url = 'form_next.php?reg_date=' . $reg_date . '&reg_no=' . $reg_no;
    header('Location:' . $url);
}

this next form, called form_next.php :

<?php
$reg_date = $_GET['reg_date'];
$reg_no = $_GET['reg_no'];
?>

<form class="form-horizontal" enctype="multipart/form-data" method="POST" action="form_p_next.php">
  <div class="form-group">
    <label class="col-sm-2 control-label">REGISTRATION DATE AGAIN</label>
    <div class="col-sm-8">
      <input type="date" class="form-control1" name="reg_date" id="focusedinput" placeholder="Default Input" value="<?php echo $reg_date; ?>">
    </div>
    <div class="col-sm-2">
      <p class="help-block">text!</p>
    </div>
  </div>
  <div class="form-group">
    <label class="col-sm-2 control-label">REGISTRATION No. AGAIN</label>
    <div class="col-sm-8">
      <input type="text" class="form-control1" name="reg_no" id="focusedinput" placeholder="Default Input" value="<?php echo $reg_no; ?>">
    </div>
    <div class="col-sm-2">
      <p class="help-block">text!</p>
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-8">
      <input name="submit" type="SUBMIT" value="Next" class="form-control1">
    </div>
  </div>
</form>

and this is process of form_next.php, called form_next_p.php

<?php
//define your code

The code work because I passing reg_date and reg_no from form_p.php to form_next.php and I use $_GET to get reg_date and reg_no and print it in input value. This is help you?

You could pass the value of reg_no as a

$_SESSION Variable

to the second form and get it there
