Form select option selected PHP - php

I try to find the way how to make option tag selected if contain current day.
For example if my string $currentDay=03; called by PHP date('d'); I would like my select like this:
<select>
<option value="01">01</option>
<option value="02">02</option>
<option value="03" selected>03</option>
<option value="04">04</option>
...
...
</select>


<?php $day=date('d');?>
<select>
<option value="01" <?=($day=='01')?'selected':'';?> >01</option>
<option value="02" <?=($day=='02')?'selected':'';?> >02</option>
<option value="03" <?=($day=='03')?'selected':'';?> >03</option>
<option value="04" <?=($day=='04')?'selected':'';?> >04</option>
...
...
</select>


You can use the following code:
$day = date('d');
$selected = ' selected="selected" ';
<select>
<option value="01" <?php if($day=='01') echo $selected; ?>>01</option>
<option value="02" <?php if($day=='02') echo $selected; ?>>02</option>
<option value="03" <?php if($day=='03') echo $selected; ?>>03</option>
<option value="04" <?php if($day=='04') echo $selected; ?>>04</option>
...
...
</select>


<select>
<? foreach ($options as $option) : ?>
<option value="<?= $option ?>" <? if ($selected_option==$option) echo 'selected' ?>>
<?= $option ?>
</option>
<? endforeach ?>
</select>

PHP Country Option list adding "select" tag with checking String value?

I want to select a target country in html.
And this code should return for example "Turkey" from my db.
<?php echo $_SESSION['user']['www']?>
I have a country list, and I use it here in settings_myinfo.php :
<select id="profile-country" name="profile_country">
<option value="Select your Country">Select your Country</option>
<?php include($root."countries_optionlist.php");?>
</select>
countries_optionlist.php :
<option value="Afganistan">Afghanistan</option>
<option value="Albania">Albania</option>
<option value="Algeria">Algeria</option>
<option value="American Samoa">American Samoa</option>
<option value="Andorra">Andorra</option>
<option value="Angola">Angola</option>
<option value="Anguilla">Anguilla</option>
<option value="Antigua & Barbuda">Antigua & Barbuda</option>
<option value="Argentina">Argentina</option>
<option value="Armenia">Armenia</option>
<option value="Aruba">Aruba</option>
<option value="Australia">Australia</option>
<option value="Austria">Austria</option>
<option value="Azerbaijan">Azerbaijan</option>
<option value="Bahamas">Bahamas</option>
<option value="Bahrain">Bahrain</option>
<option value="Bangladesh">Bangladesh</option>
<option value="Barbados">Barbados</option>
and more...
I want to add selected tag to target country like this:
<option value="Turkey" selected>Turkey</option>
I did some research on Google and StackOverflow but I couldn't find any solution.
Could you provide me with a suggestion on how to achieve this?

In each option, you can check if the session variable matches that country and add the selected attribute.
<?php $user_country = $_SESSION['user']['www']; ?>
<option value="Afganistan" <?php if ($user_country == 'Afghanistan') echo 'selected'; ?>>Afghanistan</option>
<option value="Albania" <?php if ($user_country == 'Albania') echo 'selected'; ?>>Albania</option>
<option value="Algeria" <?php if ($user_country == 'Algeria') echo 'selected'; ?>>Algeria</option>
...
You can simplify this by putting all the country names in an array. Then you can loop like this:
<?php
$user_country = $_SESSION['user']['www'];
foreach ($countries as $country) { ?>
<option value="<?php echo $country; ?>" <?php if ($user_country == $country) echo 'selected'; ?>>
<?php echo htmlspecialchars($country); ?>
</option>
<?php
}

How to set Dropdown List default value based on user selection

I have a dropdown list. However i want to set a default based on user selection. Therefore the default value is not consistent. What can i do to achieve this? I have set $country = $_POST['country']; as user selection.
<td>Country:</td>
<td colspan="2"><select name="country">
<option value="93">93-Afghanistan</option>
<option value="355">355-Albania</option>
<option value="213">213-Algeria</option>
<option value="1-684">1-684-American Samoa</option>
<option value="376">376-Andorra</option>
<option value="244">244-Angola</option>
<option value="1-264">1-264-Anguilla</option>
<option value="672">672-Antarctica</option>
<option value="1-268">1-268-Antigua and Barbuda</option>
<option value="54">54-Argentina</option>
<option value="374">374-Armenia</option>
<option value="297">297-Aruba</option>
<option value="61">61-Australia</option>
</select>
To add on. There are 200 over options (I never list all down) so i hope to get a convenience way to achieve this

You can use 'selected' for relevant option
<option value="93" <?php if($country==93) echo "selected" ?> >93-Afghanistan</option>
<option value="355" <?php if($country==355) echo "selected" ?> >355-Albania</option>
like this add if conditon for each option.

Try using session for it.
The php code:
session_start();
$_SESSION['selectedCountry'] = $_POST['country'];
Then you can use JQuery to make dropdown selected:
$(document).ready(function(){
$(function() {
$("#country").val("<?php echo $_SESSION['selectedCountry'];?>");
});
})

Please try out this ..
HTML :-
<td>Country:</td>
<td colspan="2"><select id="country" name="country">
<option value="93">93-Afghanistan</option>
<option value="355">355-Albania</option>
<option value="213">213-Algeria</option>
<option value="1-684">1-684-American Samoa</option>
<option value="376">376-Andorra</option>
<option value="244">244-Angola</option>
<option value="1-264">1-264-Anguilla</option>
<option value="672">672-Antarctica</option>
<option value="1-268">1-268-Antigua and Barbuda</option>
<option value="54">54-Argentina</option>
<option value="374">374-Armenia</option>
<option value="297">297-Aruba</option>
<option value="61">61-Australia</option>
</select>
</td>
JQuery :-
$(document).ready(function(){
$(function() {
$("#country").val("<?php echo $_POST['country'];?>");
});
})

Try this...
<?php
(isset($_POST["country"])) ? $country = $_POST["country"] : $country=93;
?>
<form action='stackover.php' method='POST'>
<select id="country" name="country">
<option <?php if ($country == 93 ) echo 'selected' ; ?> value="93">93-Afghanistan</option>
<option <?php if ($country == 355 ) echo 'selected' ; ?> value="355">355-Albania</option>
<option <?php if ($country == 213 ) echo 'selected' ; ?> value="213">213-Algeria</option>
</select>
<input type="submit" value="Submit">
</form>

Error setting the selected value from a select list

I have a HTML select list where one can chose an option.
<select name='price' id='price'>
<option value='' >Select....</option>
<option value='0-50,000' selected>0-50,000</option>
<option value='50,000-100,000'>50,000-100,000</option>
<option value='100,000-150,000'>100,000-150,000</option>
<option value='150,000-200,000'>150,000-200,000</option>
<option value='200,000 and above'>200,000 and above</option>
<option value='see all'>See All</option>
</select>
When this list is submitted via a HTML submit button, this list shows again in another page. Now, I want the option the user selected to be new selected value. I am doing this:
<select name='price' id='price'>
<option value='{$_POST['price']}'>{$_POST['price']}</option>
<option value='0-50,000'>0-50,000</option>
<option value='50,000-100,000'>50,000-100,000</option>
<option value='100,000-150,000'>100,000-150,000</option>
<option value='150,000-200,000'>150,000-200,000</option>
<option value='200,000 and above'>200,000 and above</option>
<option value='see all'>See All</option>
</select>
But values are appearing twice. The option the user selected is shown as the selected and still appears in the list. For example, we now have something like this:
0-50,000 (this is the selected value)
0-50,000
50,000-100,000
100,000-150,000
150,000-200,000
200,000 and above
How do I solve this?

In other page, make sure the selected option has selected="selected"
<select name='price' id='price'>\
<option value='' >Select....</option>
<option selected="selected" value='0-50,000'>0-50,000</option>
<option value='50,000-100,000'>50,000-100,000</option>
<option value='100,000-150,000'>100,000-150,000</option>
<option value='150,000-200,000'>150,000-200,000</option>
<option value='200,000 and above'>200,000 and above</option>
<option value='see all'>See All</option>
</select>

try this
/**
* Takes To values (First for option value Second for value to be compare)
* #param Srting $option stores Option Value String
* #param String $value Stores to be compare
* #return String
* #access public
*/
function selectBoxSelection($option, $value) {
if ($option == $value) {
return "selected";
}
}
<select name='price' id='price'>
<option value='0-50,000' <?php echo selectBoxSelection('0-50,000', $_POST['price']);?> >0-50,000</option>
<option value='50,000-100,000' <?php echo selectBoxSelection('50,000-100,000', $_POST['price']);?> >50,000-100,000</option>
<option value='100,000-150,000' <?php echo selectBoxSelection('100,000-150,000', $_POST['price']);?> >100,000-150,000</option>
<option value='150,000-200,000' <?php echo selectBoxSelection('150,000-200,000', $_POST['price']);?> >150,000-200,000</option>
<option value='200,000 and above' <?php echo selectBoxSelection('200,000 and above', $_POST['price']);?> >200,000 and above</option>
<option value='see all' <?php echo selectBoxSelection('see all', $_POST['price']);?> >See All</option>
</select>

instead of your code,
<select name='price' id='price'>
<option value='{$_POST['price']}'>{$_POST['price']}</option>
<option value='0-50,000'>0-50,000</option>
<option value='50,000-100,000'>50,000-100,000</option>
<option value='100,000-150,000'>100,000-150,000</option>
<option value='150,000-200,000'>150,000-200,000</option>
<option value='200,000 and above'>200,000 and above</option>
<option value='see all'>See All</option>
</select>
try like this,
<select name='price' id='price'>
<option value='' >Select....</option>
<?php foreach ($arr as $key=>$value)
{
if($key == $_POST['price'])
{
echo "<option selected value=$key>$value</option>";
unset($arr[$key]);
}
else
echo "<option value=$key>$value</option>";
}?>
</select>

This will do it :
<form name="myform" method="post" action="testsel.php">
<select name='price' id='price'>
<option value='' >Select....</option>
<option value='0-50,000' <?php if(isset($_POST["price"]) && $_POST["price"]=="0-50,000") print "selected"; ?>>0-50,000</option>
<option value='50,000-100,000' <?php if(isset($_POST["price"]) && $_POST["price"]=="50,000-100,000") print "selected"; ?>>50,000-100,000</option>
<option value='100,000-150,000' <?php if(isset($_POST["price"]) && $_POST["price"]=="100,000-150,000") print "selected"; ?>>100,000-150,000</option>
<option value='150,000-200,000' <?php if(isset($_POST["price"]) && $_POST["price"]=="150,000-200,000") print "selected"; ?>>150,000-200,000</option>
<option value='200,000 and above' <?php if(isset($_POST["price"]) && $_POST["price"]=="200,000 and above") print "selected"; ?>>200,000 and above</option>
<option value='see all' <?php if(isset($_POST["price"]) && $_POST["price"]=="see all") print "selected"; ?>>See All</option>
</select>
<input type="submit" value="submit">
</form>
<?php
if(isset($_POST["price"]))
print $_POST["price"];
?>
Save this file as "testsel.php" and view. It will serve the purpose.

<select name='price' id='price'>
<option value='' >Selec</option>
<option value='0-50,000'<?php if($_POST['price']=='0-50,000'){echo "selected==selected";}?>>0-50,000</option>
<option value='50,000-100,000'<?php if($_POST['price']=='50,000-100,000'){echo "selected==selected";}?>>50,000-100,000</option>
<option value='100,000-150,000'<?php if($_POST['price']=='100,000-150,000'){echo "selected==selected";}?>>100,000-150,000</option>
<option value='150,000-200,000'<?php if($_POST['price']=='150,000-200,000'){echo "selected==selected";}?>>150,000-200,000</option>
<option value='200,000 and above'<?php if($_POST['price']=='200,000 and above'){echo "selected==selected";}?>>200,000 and above</option>
<option value='see all'<?php if($_POST['price']=='see all'){echo "selected==selected";}?>>See All</option>
</select>

Removing duplicated options from select box in PHP

I want to generate select boxes based on the number of elements in the $chosen array and each of them will have the default selected options. The first one is A, and the second one is D. The following code is almost okay except I want to remove the duplicated options. Here's the output:
<select>
<option>Select</option>
<option value="A" selected="selected">A</option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
<option value="D">D</option>
<option value="E">E</option>
</select>
<select>
<option>Select</option>
<option value="D" selected="selected">D</option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
<option value="D">D</option>
<option value="E">E</option>
</select>
I tried array_merge with array_unique to merge $options and $chosen before foreach($options as $option) but it isn't working. Can anyone suggest a solution?
<?php
$options = array("A","B","C","D","E");
$chosens = array("A","D");
foreach($chosens as $chosen)
{
print "<select><option>Select</option>";
if(in_array($chosen,$options))
{
print "<option value='".$chosen."' selected='selected'>$chosen</option>";
}
/* $options = array_unique(array_merge($chosen,$options)); */
foreach($options as $option)
{
print "<option value='".$option."'>$option</option>";
}
print "</select>";
}
?>*

Actually, just a simple if condition is enough. Like this:
<?php
$options = array("A","B","C","D","E");
$chosens = array("A","D");
?>
<?php foreach($chosens as $chosen): ?>
<select name="">
<?php foreach($options as $option): ?>
<option value="<?php echo $option; ?>" <?php echo ($option == $chosen) ? 'selected' : ''; ?>><?php echo $option; ?></option>
<?php endforeach; ?>
</select><br/>
<?php endforeach; ?>

How to temporarily hold the option value I selected in session?

I am new to PHP. I have a problem. I have a simple HTML form where when I select the country from select / option list provided, i want PHP to echo message on country I selected. Also I want PHP include function to list the form specific to that country name (by concatanating). Can someone please help me by pointing where I went wrong. I am new to PHP, self taught and have no idea if this approach is correct. Thanks in advance for anticipated help.
<pre>
<form name="form1" method="post" action="component_project_in_countries.php">
<label for="country">View outlets in which country? </label>
<select name="country_chosen" onchange="document.form1.submit()" id="country">
<option value="">All Middle Eastern Countries</option>
<option value="Iraq">Iraq</option>
<option value="Kuwait">Kuwait</option>
<option value="Bahrain">Bahrain</option>
<option value="Saudi">Saudi Arabia</option>
<option value="Qatar">Qatar</option>
<option value="Oman">Oman</option>
<option value="Yemen">Yemen</option>
<option value="Jordan">Jordan</option>
<option value="Israel">Israel</option>
</select>
</form>
<br>
<?php
$country_selected = '';
$country_selected = $_POST['country_chosen'];
echo "You have chosen to view outlets in " . $country_selected;
include ("inc/OutletsIn" . $country_selected .".php";)
?>
</pre>
Thank you for your help on my earlier post. I am able to echo out and concatenate file name in PHP include. But I have a new problem. The option value i selected (country name) does not get displayed in the box. How can i hold the chosen value for the session. Please advise.
Thank you again.

First check that a value has been given to $_POST['country_chosen'] with isset(). Then remove that extra semi-colon that is causing a syntax error (in your include()) statement:
if(isset($_POST['country_chosen'])){
$country_selected = $_POST['country_chosen'];
echo "You have chosen to view outlets in " . $country_selected;
include("inc/OutletsIn" . $country_selected .".php");
}
Includes something (like) inc/OutletsInIsrael.php

if(!empty($_POST['country_chosen'])){
$country_selected = $_POST['country_chosen'];
echo "You have chosen to view outlets in " . $country_selected;
require "inc/OutletsIn".$country_selected.".php";
//no brackets required
} else { /* throw error */ }

Here is your updated code, just copy & replace :
component_project_in_countries.php
<pre>
<form name="form1" method="post" action="component_project_in_countries.php">
<label for="country">View outlets in which country? </label>
<select name="country_chosen" onchange="document.form1.submit()" id="country">
<option value="">All Middle Eastern Countries</option>
<option value="Iraq">Iraq</option>
<option value="Kuwait">Kuwait</option>
<option value="Bahrain">Bahrain</option>
<option value="Saudi">Saudi Arabia</option>
<option value="Qatar">Qatar</option>
<option value="Oman">Oman</option>
<option value="Yemen">Yemen</option>
<option value="Jordan">Jordan</option>
<option value="Israel">Israel</option>
</select>
</form>
<br>
<?php
if(isset($_POST['country_chosen']))
{
$country_selected = '';
$country_selected = $_POST['country_chosen'];
echo "You have chosen to view outlets in " . $country_selected;
include ("inc/OutletsIn" . $country_selected .".php");// here you have added `;` on wrong place.
}
?>
</pre>
New answer, Just replace the code of select box :
<select name="country_chosen" onchange="document.form1.submit()" id="country">
<option value="">All Middle Eastern Countries</option>
<option value="Iraq" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Iraq')) echo 'selected' ?> >Iraq</option>
<option value="Kuwait" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Kuwait')) echo 'selected' ?> >Kuwait</option>
<option value="Bahrain" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Bahrain')) echo 'selected' ?> >Bahrain</option>
<option value="Saudi" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Saudi')) echo 'selected' ?> >Saudi Arabia</option>
<option value="Qatar" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Qatar')) echo 'selected' ?> >Qatar</option>
<option value="Oman" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Oman')) echo 'selected' ?> >Oman</option>
<option value="Yemen" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Yemen')) echo 'selected' ?> >Yemen</option>
<option value="Jordan" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Jordan')) echo 'selected' ?> >Jordan</option>
<option value="Israel" <?php if(isset($_POST['country_chosen']) && ($_POST['country_chosen']=='Israel')) echo 'selected' ?> >Israel</option>
</select>
