Chose select atribute in form based on variable value - php

I want the value of a select in a form to be selected based on the value of a variable. Below is the code that I tried, although I always get the value female in that select, for what I suppose the select parameter is always being applied. What is the correct way to accomplish this?
<li><label for="sex">Sex:</label>
<select name="sex">
<option value="male" selected="<?php if(strcmp($Sex, 'male') ==0)echo 'select'; ?>">Male</option>
<option value="female" selected="<?php if(strcmp($Sex, 'female') ==0)echo 'select'; ?>">Female</option>
</select></li>

<select> <option value="male" <?php if($Sex == 'male')echo 'selected="selected"'; ?>>Male</option>
<option value="female" <?php if($Sex == 'female')echo 'selected="selected"'; ?> >Female</option>
</select>
Empty selected="" is the same as selected="selected"

How to display the multiple data on sumoselect dropdown from the database?

I am using sumoselect (http://hemantnegi.github.io/jquery.sumoselect/sumoselect_demo.html) and CodeIgniter. I am displaying data from the database. I am inserting product type multiple data in the database like
producttype
1
1+2
1+2+3
I am displaying like this on HTML page
<select name="producttype[]" class="form-control multipleselect event_stop" id="producttype" multiple="multiple">
<option value="" selected disabled>Select</option>
<option value="1" <?php if($post->producttype =="1") echo 'selected'; ?>>One</option>
<option value="2" <?php if($post->producttype =="2") echo 'selected'; ?>>Two</option>
<option value="3" <?php if($post->producttype =="3") echo 'selected'; ?>>Three</option>
<option value="4" <?php if($post->producttype =="4") echo 'selected'; ?>>Four</option>
</select>
If I am getting 1 from the database then select dropdown displaying One but sometimes I am getting 1+2 or 1+2+3 then how can I show in the select dropdown?
Would you help me out in this?
I don't have any knowledge of sumoselect but it may help you to show selected multiple options as
$producttype_array = explode("+","1+2+3");
<select name="producttype[]" class="form-control multipleselect event_stop" id="producttype" multiple="multiple">
<option value="1" <?php if(in_array(1,$producttype_array)) echo 'selected'; ?>>One</option>
<option value="2" <?php if(in_array(2,$producttype_array)) echo 'selected'; ?>>Two</option>
<option value="3" <?php if(in_array(3,$producttype_array)) echo 'selected'; ?>>Three</option>
<option value="4" <?php if(in_array(4,$producttype_array)) echo 'selected'; ?>>Four</option>
</select>

drodown list php

I have a profile page in php for the user to set up his profile. The profile page prompts the user to set the gender.This is the code:
<form action='database.php' method=post>
<select name="myvalue">
<option value=" ">--select--</option>
<option value="male">male</option>
<option value="female">female</option>
</select>
<input type=submit>
</form>
after the user selects the gender, the following code gets the selection
$myvalue=$_POST['myvalue'];
and then by using a function stores value in database.
Next time that the user will visit his profile page, I want the dropdown list to show the value that selected before. For example lets say that the user selects as gender "male" the first time created his profile. If he visits again the profile page, the dropdown list must have automated as selected value, the value "male".
Try this :
<?php
$gender = /// fetch value from database
?>
<form action='database.php' method=post>
<select name="myvalue">
<option value=" ">--select--</option>
<option value="male" <?php if($gender == "male"){?> selected="selected" <?php }?>>male</option>
<option value="female" <?php if($gender == "female"){?> selected="selected" <?php }?>>female</option>
</select>
<input type=submit>
</form>
To set a option field as default selected you can use the selected keyword
<select name="myvalue">
<option value=" ">--select--</option>
<option value="male" selected>male</option>
<option value="female">female</option>
</select>
if you use xml document type you have to use
<select name="myvalue">
<option value=" ">--select--</option>
<option value="male" selected="selected">male</option>
<option value="female">female</option>
</select>
it's up to you to load values from cookie or database for that user and then perform checks to echo the "selected" value into that option field
Just check agains value and show selected="selected" in html
<?php
$value = $_POST['myvalue'];
?>
<form action='database.php' method=post>
<select name="myvalue">
<option value=" " <?php echo $value==' ' ? 'selected="selected"' : ''; ?> >--select--</option>
<option value="male" <?php echo $value=='male' ? 'selected="selected"' : ''; ?> >male</option>
<option value="female" <?php echo $value=='female' ? 'selected="selected"' : ''; ?> >female</option>
</select>
<input type=submit>
</form>
Something like this:
<form action='database.php' method=post>
<select name="myvalue">
<option value=" ">--select--</option>
<option value="male" <?php echo $gender=="male"?"selected":""; ?>>male</option>
<option value="female" <?php echo $gender=="female"?"selected":""; ?>>female</option>
</select>
<input type=submit>
</form>
But better would be to use a decent template system.
add selected attribute to the option
<select name="myvalue">
<option value=" ">--select--</option>
<?php
$selected = 'selected="selected" ';
foreach(array('male', 'female') as $v){
echo '<option '.(($v==$dbgender)? $selected : '').'value="'.$v.'">'.$v.'</option>';
}
?>
</select>
$dbgender is the value that stored for that user.
Do validation like this.
$val = value_from db;
if($val == "male") {
echo '<option value="male" selected="selected">male</option>';
} elseif($val == "female") {
echo '<option value="female" selected="selected">female</option>';
}

How to set selected value in drop list in HTML?

How to set selected value in drop list in HTML in Edit Form?
The selected value came from MySql
This code is not work !! >> selected=""
<select name="TutorGender" id="TutorGender" selected="<?php echo $Gender ?>">
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
W3Schools does a good job of explaining this here
http://www.w3schools.com/tags/att_option_selected.asp
Your code might look something like this.
<select name="TutorGender" id="TutorGender">
<option value="Male" <?php if($Gender == "Male") echo "selected"; ?>>Male</option>
<option value="Female" <?php if($Gender == "Female") echo "selected"; ?>>Female</option>
</select>
Though my PHP syntax may be a little off, but you should get the idea.
Selected goes on the option tag, not on the select tag.
<select name="TutorGender" id="TutorGender" >
<option value="Male" selected="selected">Male</option>
<option value="Female">Female</option>
</select>
<select name="TutorGender" id="TutorGender">
<option value="Male" <?php if($Gender=='Male') echo 'selected' ?>>Male</option>
<option value="Female" <?php if($Gender=='Female') echo 'selected' ?>>Female</option>
</select>
The selected attribute appears on the option(s) that should be selected, not the select element (if it went on the select element itself, then (since multiple options can be selected at the same time) it would have to take a list of ids and you would need to add an id to each option).
<option value="foo" selected>Foo</option>
Generally you would have an array of values (or of value/human text pairs) that you would loop over. (i.e. you wouldn't hard code your options)
You would generate one option each time you went around the loop, and test to see if you should include a selected attribute each time.
<option <?php if($Gender == 'Male'){ echo(' selected '); } ?> value="Male">Male</option>
<option <?php if($Gender == 'Female'){ echo(' selected '); } ?> value="Female">Female</option>
<select name="TutorGender" id="TutorGender">
<?php
$genders = array( 'Male', 'Female' );
foreach( $genders as $value )
{
$selected = ( $Gender == $value )? ' selected="selected"': '';
echo '<option value="' . $value . '"' . $selected . '>' . $value . '</option>';
}
?>
</select>
just another way of doing it. I prefer to use shorthand if statements for code such as this.
<select name="TutorGender" id=\"TutorGender\">
<option value="Male" <?php echo ($Gender == "Male" ? "selected" : ""); ?>>Male</option>
<option value="Female" <?php echo ($Gender == "Female" ? "selected" : ""); ?>>Female</option>
here is a link to using shorthand "if" statements.
In a case where I needed to use a select as part of a user update form that was populated via a database I found the array option works best. The line by line option can get very unwieldy very quickly. This way you simply need to add an option to the $optionDept array should any new options be required. In this example "$row['Dept']" is from the larger overarching results from the database request.
$optionDept= array('sales','warehouse','inspection','production','accounts','admin','inactive');
$optionCount= count($optionDept);
echo"<select name=\"UserDept\">";
for($x = 0; $x < $optionCount; $x++) {
echo"<option value=".$optionDept[$x];
if($optionDept[$x]==$row['Dept']){echo " selected";}
echo">".$optionDept[$x]."</option>";}
echo"</select</P>
try this
if you want to keep male as selected
<select name="TutorGender" id="TutorGender" >
<option value="Male" selected="selected">Male</option>
<option value="Female">Female</option>
</select>
This worked for me: I send througt the GET method of the submit the value i want to restore, and then in the php, AT THE END OF THE PAGE (if not, default values will be set if the code is before the php) i set those values.
echo "select_language.selectedIndex = ".$_GET['iL'].";";

Setting the selectedindex property of an HTML dropdown using PHP

From the database I pull back the user information and based on this I can determine the correct index value using a case statement:
<?php
$genderIndex = 0;
switch ($displayProperties['gender'])
{
case "":
$genderIndex = 0;
break;
case "Male":
$genderIndex = 1;
break;
case "Female":
$genderIndex = 2;
break;
case "Other":
$genderIndex = 3;
break;
}
?>
On the form I have an HTML dropdown (select):
<select name="gender" selectedIndex="<?php echo $genderIndex; ?>">
<option value="0"> </option>
<option value="Male">Male</option>
<option value="Female">Female</option>
<option value="Other">Other</option>
</select><br/>
The problem is it never works and always loads the page at index=0 and I made sure to verify if $genderIndex actually has the expected value (it does).
What am I doing wrong?
selectedindex property is not used in this way, for appropriate use of the selectedindex property you can view http://www.w3schools.com/jsref/prop_select_selectedindex.asp.
Instead what you are after is applying the "selected" attribute to the appropriate option. The code below runs some shorthand if/else checks and will apply the "selected" attribute where appropriate, based on your $genderIndex you created in your function given.
<select name="gender">
<option value="0" <?php echo ($genderIndex==0)?('selected'):(''); ?>"> </option>
<option value="Male" <?php echo ($genderIndex==1)?('selected'):(''); ?>>Male</option>
<option value="Female" <?php echo ($genderIndex==2)?('selected'):(''); ?>>Female</option>
<option value="Other" <?php echo ($genderIndex==3)?('selected'):(''); ?>>Other</option>
</select><br/>
The reason this is not working is because selectedIndex is not a valid attribute on the HTML <select/> element. (See http://www.w3.org/TR/html4/interact/forms.html#h-17.6)
To pre-select an option in the <select/> element (other than the first one, in this an empty value), you need to have your HTML output look something like this:
<select name="gender">
<option value="0"> </option>
<option value="Male">Male</option>
<option value="Female" selected="true">Female</option>
<option value="Other">Other</option>
</select>
Notice the addition of the selected="true" on the second <option/> tag. Something like the following will get the job done but is hardly elegant.
<select name="gender">
<?php
if(0 == $genderIndex)
echo '<option value="0" selected="true"> </option>';
else
echo '<option value="0"> </option>';
if(1 == $genderIndex)
echo '<option value="Male" selected="true">Male</option>';
else
echo '<option value="Male">Male</option>';
if(2 == $genderIndex)
echo '<option value="Female" selected="true">Female</option>';
else
echo '<option value="Female">Female</option>';
if(3 == $genderIndex)
echo '<option value="Other" selected="true">Other</option>';
else
echo '<option value="Other">Other</option>';
?>
</select>
A good web framework can be helpful here. I know that in Java, the Struts framework assists with echoing a <select/> tag to the output with the appropriate <option/> selected.
That's not how you specify the selected <option> in HTML. You need to have the selected attribute on the <option> itself, like so:
<select name="gender">
<option value="0"> </option>
<option value="Male" selected>Male</option>
<option value="Female">Female</option>
<option value="Other">Other</option>
</select><br/>

Change selected option in select (form)

I have an intial group of options like these:
<select name="item[type]">
<option value="0" class="dr">First</option>
<option value="1" class="dr">Second</option>
<option value="2" class="dr">Third</option>
<option value="3" class="dr">Fourth</option>
</select>
I want to check if a variable isset($test) is defined. If it is, then I want to change the option selected where the value is equal of $test. Something like this <OPTION SELECTED>
For example. $test = 3; so, the option selected should be fourth. If $test is empty or not defined, then the first should be the option that is selected.
One way:
<select name="item[type]">
<option <?=$test==0?'selected="selected"':'';?> value="0" class="dr">First</option>
<option <?=$test==1?'selected="selected"':'';?> value="1" class="dr">Second</option>
<option <?=$test==2?'selected="selected"':'';?> value="2" class="dr">Third</option>
<option <?=$test==3?'selected="selected"':'';?> value="3" class="dr">Fourth</option>
</select>
Another:
<? $selected[$test] = 'selected="selected"'; ?>
<select name="item[type]">
<option <?=$selected[0];?> value="0" class="dr">First</option>
<option <?=$selected[1];?> value="1" class="dr">Second</option>
<option <?=$selected[2];?> value="2" class="dr">Third</option>
<option <?=$selected[3];?> value="3" class="dr">Fourth</option>
</select>
<select name="item[type]" id="selectBoxId">
<option value="0" class="dr">First</option>
<option value="1" class="dr">Second</option>
<option value="2" class="dr">Third</option>
<option value="3" class="dr">Fourth</option>
</select>
<script type="text/javascript">
var test = "<?= $test; ?>";
if (test != '' && parseInt(test)) {
document.getElementById('selectBoxId').selectedIndex = test;
}
</script>
Remove "[type]" from select name, make it simple to "item".
Then execute this code.
$test = isset($_POST['item']) ? $_POST['item'] : "0";
// assuming you are using a loop: in the loop where you create the options
$selected_html = $test == $loop_var ? ' selected="selected" ' : '';
echo "<option value=\"$loop_var\" class=\"dr\"$selected_html>$text</option>";
