# flexy:nameuses="variable"

flexy:nameuses="variable" -- Use a variable in the name for a flexy form element

## Synopsis

``Usage` (flexy:nameuses="variable" name="sometag[%s]")`

## Description

If you have a form with multiple input boxes (eg. group members), which are dynamically generated, then this attribute can be used to generate flexy elements based on sprintf'ing the variable value into the name attribute value.

## Example

Example 41-1. Template with flexy:ignore
    <html>
      <head>
        <title>Example of name Uses</title>
      </head>
      <body>
        <form name="formtest">
          <span flexy:foreach="data,key,row">
            {key}: <input name="data%s" flexy:nameuses="key" type="hidden" size="10"><br>
          </span>
        </form>
      </body>
    </html>

Example 41-2. Backend Code Snippet
    <?php
    $this->data = array();
    $elem = array();
    $elem['formtest'] = &new HTML_Template_Flexy_Element();
    $elem['formtest']->attributes['method'] = 'post';
    $elem['formtest']->attributes['action'] = 'test';

    for($i = 0; $i < 10; $i++) {
            $this->data[$i] = $i;

            $elem["data$i"] = new HTML_Template_Flexy_Element();
            $elem["data$i"]->attributes['type'] = 'text';
            $elem["data$i"]->attributes['size'] = $i;

    }
    $flexy->outputObject($this, $elem);

    ?>

Example 41-3. Compiled template
    <html>
      <head>
        <title>Example of name Uses</title>
      </head>
      <body>
        <?php echo $this->elements['formtest']->toHtmlnoClose();?>
    <?php if ($this->options['strict'] || (is_array($t->data)  || is_object($t->data)))
    foreach($t->data as $key => $row) {?>
          <?php echo htmlspecialchars($key);?>: <?php if (!isset($this->elements[sprintf('data%s',$key)])) $this->elements[sprintf('data%s',$key)]= $this->elements['data%s'];
                    $this->elements[sprintf('data%s',$key)] = $this->mergeElement($this->elements['data%s'],$this->elements[sprintf('data%s',$key)]);
                    $this->elements[sprintf('data%s',$key)]->attributes['name'] = sprintf('data%s',$key);
                    echo $this->elements[sprintf('data%s',$key)]->toHtml();?><br>
    <?php }?>
        </form>
      </body>
    </html>
