How to keep showing selected option from drop down list? - php

I have a drop down list where I select options
<form action="" method="POST" class="styled-select">
<select name="seasons" onchange='this.form.submit()'>
<option value="">Select a Season</option>
<option value="1">2002/2003</option>
<option value="2">2003/2004</option>
<option value="3">2004/2005</option>
<option value="4">2005/2006</option>
<option value="5">2006/2007</option>
<option value="6">2007/2008</option>
<option value="7">2008/2009</option>
<option value="8">2009/2010</option>
<option value="9">2010/2011</option>
<option value="10">2011/2012</option>
<option value="11">2012/2013</option>
<option value="12">2013/2014</option>
</select>
<noscript><input type="submit" value="Submit"></noscript>
</form>
You can see the list here footystat
I am using the following PHP
if(isset($_POST['seasons'])){ $seasonette = $_POST['seasons']; }
if(isset($_POST['year'])){ $yearette = $_POST['year']; }
if(isset($_POST['comp'])){ $competitionette = $_POST['comp']; }
if(isset($_POST['which'])){ $whichette = $_POST['which']; }
When I select something from the list, I want selected item in the list to continue showing. At the moment when I select (for example) 2013/2014, it will show the results but the drop down menu goes back to its original state instead of showing 2013/2014.

Get Option value selected when it gets posted value, like this,
<option value="1" <?php if(isset($_POST['seasons']) && $_POST['seasons'] == '1'){ ?> selected="selected" <?php } ?>>2002/2003</option>
Set value like this for each option

You can set the "selected" property to the option , just like you set a value !
<option value="8" selected>2009/2010</option>
Use a if statement in PHP to determine which one should be selected.

Thats because the page refreshes.
On page load check if there is post variable than match the value with each option's HTML and write selected attribute.

The shorter way is
<option value="1" <?php echo $_POST['seasons']==1?"selected":""; ?>2002/2003</option>

How do I Pass Values from One Form to Another?

I have this form:
<form name="summaryform">
<select name="category" id="category" style="width:500px;">
<option value="">Choose category...</option>
<option value="ActionScript">ActionScript</option>
<option value="AppleScript">AppleScript</option>
<option value="Asp">Asp</option>
<option value="BASIC">BASIC</option>
<option value="C">C</option>
<option value="C++">C++</option>
<option value="Clojure">Clojure</option>
<option value="COBOL">COBOL</option>
<option value="ColdFusion">ColdFusion</option>
<option value="Erlang">Erlang</option>
<option value="Fortran">Fortran</option>
<option value="Groovy">Groovy</option>
</select><br>
<select name="subcategory" id="subcategory" style="width:500px;">
<option value="">Choose sub category...</option>
<option value="Haskell">Haskell</option>
<option value="Java">Java</option>
<option value="JavaScript">JavaScript</option>
<option value="Lisp">Lisp</option>
<option value="Perl">Perl</option>
<option value="PHP">PHP</option>
<option value="Python">Python</option>
<option value="Ruby">Ruby</option>
<option value="Scala">Scala</option>
<option value="Scheme">Scheme</option>
</select><br>
<input type="text" name="comments" id="comments" value=" Enter request comments..." onfocus="clearText(this)" onblur="restoreText(this)" style="width:493px;color:#999;font-size:9pt;height:20px;">
On the form above, I have two dropdowns (name="categoryId" and "subcategoryid") and one textboxt (name="comments")
How do I pass the values from this form to another form?
Let's say below is the form I want to pass the values to:
<div>
<p>
<form name="summaryform" method='POST' action='process.php'>
<div style="font-size:12pt;">
value from one dropdown
value from the other dropdown
value from textbox
</form>
</p>
</div>
jQuery Method
If the forms are on the same page, you can use jQuery to get the values and write to the div:
var content = $('#category').val()+'<br>'+$('#subcategory').val()+'<br>'+$('#comments').val();
$('#div-to-write-to').html(content);
PHP Method
If the forms are on different pages, you will need to use PHP and the $_POST[] variable to pass the values you are looking for.
NOTE: for this method to work the page being POSTed to MUST be PHP. You will also need to add an action and method in the first form to POST to the second form.
This would be the code in the form on the page being POSTed to:
<?php echo $_POST['category'].'<br>'.$_POST['subcategory'].'<br>'.$_POST['comments']; ?>
A value can be passed between forms using the POST and GET methods. The first form (Which is sending the values) does not have this defined, so modify the first form to this -
<form name="summaryform" method='POST' action='process.php'>
Then, in process.php, put the following php code -
$dropdown_first = $_POST['category'];
$dropdown_second= $_POST['subcategory'];
$comment = $_POST['comments'];
After that, you can just use the variables as you see fit!
If you want just print the selected values from first form #zsaa14's
answer is good
If you want to print whole select list, autoselected your value, heres a code.
foreach($categories as $category) {
$selected = $category['name'] === $_POST['category'] ? 'selected="selected"' : '';
echo " <option value="{$category['name']}" {$selected}>{$category['name']}</option>" ;
}
NOTE: the variable names and keys are for example, use Yours. This is only fragment of code.
You can use post data fields to send the values to the next form

How to select the dropdownlist value and validate it

I have created the dropdown list in my index page i want to select the one value from that list and validate it if not selected any value the code for that is as follows:
<form action="" method="post">
<select value="state" name="state">
<option selected="">---please enter---</option>
<option value="1">andhra</option>
<option value="2">thamil</option>
<option value="3">kerela</option>
</select>
</form>
php code for the above file is as follows:
<?php
if(!empty($_POST['state'])) {
$state = $_POST['state'];
}
else {
echo "required";
}
?>
I dont want to be select the first option in selection list please enter to be selected but the code which I have used is taking that value also I want relevant code how to validate that list?
I prefer adding a disabled attribute to the placeholder option, that way, a user has to choose something if they click the drop-down:
<select value="state" name="state">
<option selected disabled>---please enter---</option>
<option value="1">andhra</option>
<option value="2">thamil</option>
<option value="3">kerela</option>
</select>
Quick demo: http://jsfiddle.net/hxxJZ/
something like this should to the trick:
<form action="" method="post">
<select name="state">
<option value="0" selected>---please enter---</option>
<option value="1">andhra</option>
<option value="2">thamil</option>
<option value="3">kerela</option>
</select>
</form>
php
<?php
if( 0 != $_POST['state'] ) {
$state = $_POST['state'];
}
else {
echo "required";
}
?>
your HTML is not right,
try edit this line
<option selected=""...
to this one
<option selected value="">---
select elements do not have an (HTML) value attribute, so remove value="state".
The selected attribute should be selected="selected" (or just SELECTED).

dropdown list with 2 values

I need to create a dropdownlist which has two values "OK" and "NOK" one should be selected by default based of an value of $Status. The user should than be able to change the selection or let the default one. How can i manage this? What i have tried:
<select name="Status">
<option value="OK">OK selected="selected"</option>
<option value="NOK">NOK</option>
</select>
<select>
<option value="OK" <?php if($Status == "OK") echo 'selected="selected"';?>>OK</option>
<option value="NOK" <?php if($Status == "NOK") echo 'selected="selected"';?>>NOK</option>
</select>
You can add an id and/or name attribute to the select as you like.

How to ?
Indeed, you only get the value. If you need more, just encode whatever you want into the value, for example:
<option value="Item3.SubItem5">SubItem5</option>
Alternatively, you could use javascript to catch onChange events on the select field and update a hidden input field with the desired label.
you could make the values arrays e.g.
<option value="Item3[SubItem5]">SubItem5</option>
so then your $_POST['category'] should return an array

HTML define what selection option is active

I have a select box with the following (it has been shortened):
<select id="viewSelector" name="when" style="width:92%;">
<option value="USA">USA</option>
<option value="Australia">Australia</option>
<option value="Germany">Germany</option>
</select>
If the user logs into the control panel and wants to change his country, he gets presented with this form. My problem is that everytime USA is the default and I can not change this depending on the users country. For example, the user lives in Australia. He wants to change his country to USA and goes to this page. I want the country that is displayed to be Australia. Let me know if this makes sense.
To preselect a value, just add the selected attribute to the desired option.
<select id="viewSelector" name="when" style="width:92%;">
<option value="USA">USA</option>
<option value="Australia" selected="selected">Australia</option>
<option value="Germany">Germany</option>
</select>
This will preselect Australia for example.
You need to add a selected attribute to the option you want to select, as described in the spec.
<select id="viewSelector" name="when"">
<option value="USA">USA</option>
<option value="Australia" selected="selected">Australia</option>
<option value="Germany">Germany</option>
</select>
In your script, you need to emit this attribute for whatever default you want to display.
Use the selected attribute of the option tag.
<select id="viewSelector" name="when" style="width:92%;">
<option value="USA">USA</option>
<option value="Australia">Australia</option>
<option selected value="Germany">Germany</option>
</select>
Use selected on the <option> tag that names the user's current country:
<option value="Australia" selected="selected">Australia</option>
So in PHP:
<select>
<?php
$countries = array('USA', 'Australia', 'Germany');
$current_country = 'Australia';
foreach($countries as $country) {
if($country == $current_country) {
echo '<option selected="selected">'.$country.'</option>';
} else {
echo '<option>'.$country.'</option>';
}
}
?>
</select>
The html looks like:
<option selected value="Australia">Australia</option>
In the php loop that builds this html, compare the current option name with the user's current country (retrieved from a database or where-ever). When the two match, add selected
A bit shorter:
foreach($paises as $key=>$value)
{
if($key == "PE"){$activo = ' selected="selected" '; }else{$activo = "";}
echo "<option $activo value=\"$key\">$value</option>";
}
