make a link from an array variable

[whitetulip]

Hello everybody,
anyone can help me with this problem?
instead of just display the child (in array)..echo $Valuechild[$i]."; ";
(see the below code)..I would like to make a link from $Valuechild[$i] to a details of that variable..

here is the full code

<TEXTAREA NAME="comments3" style='width:50%' rows='4'>
      <?php
        for ($i =0; $i < $ValuenumtableChildren; $i++)
 
      {
 
      echo '<a href="viewingdetails.php?name='.$Valuechild[$i].'</a>';
 
      }
      ?>
 
      </TEXTAREA>

hope someone can help me..I have tried so many ways to do this..
many thanks.

Not sure what you are after here, but if you want that to be a correctly formatted html link change it to this:

echo '<a href="viewingdetails.php?name=' 
          . $Valuechild[$i] . '">' . $Valuechild[$i] 
          . '</a>' . PHP_EOL; 

I split the line to help improve readability, I hope.

hi, thanks for your help..
But it appears like this.

<a href="viewingdetails.php?name=Matter in Nature">Matter in Nature</a>

it seems that a href does not work here..not translated to html format..
What I wanted to do is to make a link from Matter in Nature..or whatever childs it is to a detail page..I have tried several syantax but it still appear like the above result.

Any other suggestion please?
thanks

Could you give us an example of the link you want to produce? The code you posted implies you want to produce a link as per Cups' post.

[whitetulip]

Hi,
I think what did he meant is similar to me..
to make a link from a variable $Valuechild[$i] .
the problem is that the output is not as what expected..
It should be like this
Matter in Nature

however the output displayed is like this..

<a href="viewingdetails.php?name=Matter in Nature">Matter in Nature</a>.
href is appear in the output..it should be a link , shouldn't it?

many thanks for your help

I think you must use urlencode( $Valuechild[$i] );

is that what you want?

I have tried this and there is an error on that line..syntax error .

Your problem is that you are trying to have a link inside a textarea.

Bottom line is that textareas are for editing, so HTML isn't rendered inside them.

ic..ok thanks..

so, what should I do now.. I do not have an idea about it..
thank you

Well, why do you want to put a link inside a control designed for user-input anyway?

[Cups]

echo '<a href="viewingdetails.php?name=' 
          . urlencode( $Valuechild[$i] ) . '">' . $Valuechild[$i] 
          . '</a>' . PHP_EOL; 

Some of the problems you are encountering are to do with basic HTML.

e.g. $Valuechild[1] clearly contain spaces, browsers will do odd things with that, as explained, links inside a textarea may not display exactly as you expect etc.

We all had to learn this stuff the hard way.

You might benefit a lot from first of all creating your 'page' in basic HTML and get your forms working as you expect. Then slowly get PHP to generate that page for you.

ok..it is not a user input actually..
when user key-in a keyword ( in differenet page)..any related term to that keyword will appear as a child value here..
then.. if users click the child value..(in this case: Matter in Nature)..all records that contains that term will be displayed in a detail page..

hope someone can helps
thanks

You are using the wrong element for this then.

You should be using a <select size="..."> element, with the size being the number of items you want to show before scrolling.

You then put each related term into an option element.

So, for example, your code could be:

<select size="6">
    <?php
    foreach(getRelatedKeywords($InputKeyword) as $Keyword){
        echo "<option>{$Keyword}</option>";
    }
    ?>
</select>

If you want the form to submit right away, you'd use:

<select size="6" onchange="form.submit()">
    <?php
    foreach(getRelatedKeywords($InputKeyword) as $Keyword){
        echo "<option>{$Keyword}</option>";
    }
    ?>
</select>

[whitetulip]

still doesn't work.
anyway, thanks all for your kind help, suggestions, comments and input

HI arkinstall..Could you pease elaborate this in details..
Really have to make it works.

You should be using a <select size="..."> element, with the size being the number of items you want to show before scrolling.

You then put each related term into an option element.

So, for example, your code could be:

<select size="6">
    <?php
    foreach(getRelatedKeywords($InputKeyword) as $Keyword){
        echo "<option>{$Keyword}</option>";
    }
    ?>
</select>

the output that should be displayed here are variables in array. (can refer to my previous posts in this thread.
COuld you please explain this?
thank you.

[Jake Arkinstall]

The function GetRelatedKeywords($InputKeyword) should be replaced with the array you get for grabbing the related keywords.

[whitetulip]

is this what did you mean?

 <select size="2">
 
<?php
for ($i =0; $i < $ValuenumtableChildren; $i++)
{

    
    foreach(getRelatedKeywords($Valuechild[$i].) as $Keyword){
        echo "<option>{$Keyword}</option>";
    }
    
?>    
<?php
}
?>    
</select>

I tried this as well

<textarea name="comments3" style='width:50%' rows='4'>
<?php
for ($i =0; $i < $ValuenumtableChildren; $i++)
{
    foreach(getRelatedKeywords($Valuechild[$i].) as $Keyword){
        echo "<option>{$Keyword}</option>";
    }
?>    
<?php
}
?>    
</textarea>

both do not work.
really need your help.
the ($Valuechild[$i].) are displayed correctly..just to make a link form it.

thanks

Ok, so to make it act like a link you'd need some JS to fire it:

<form action="viewingdetails.php" method="get">
    <select size="2" name="name" onChange="form.submit();">
        <?php
            foreach($ValuenumtableChildren as $Keyword){
                echo "<option>{$Keyword}</option>";
            }
        ?>
    </select>
    <input type="submit" value="Go > " /> <!-- This is needed for those without JavaScript -->
</form>

[whitetulip]

hi..thanks for your input.
I have tried it..but there is no value appear.
the variable - $ValuenumtableChildren- is not read as keyword.

the whole code is like this..thank you

</p>
  <p>Children: </p>
 
<p>    
<form action="viewingdetails.php" method="get">
    <select size="6" name="name" onChange="form.submit();">
        <?php
            foreach($ValuenumtableChildren as $Keyword){
                echo "<option>{$Keyword}</option>";
            }
        ?>
    </select>
    <input type="submit" value="Go > " /> 
</form>
</p>
