    <p>Hopefully someone will be able to tell me how to keep user quotes when generating an image. What I mean is if a user submits words like:</p> <blockquote> <p>don't</p> </blockquote> <p>or</p> <blockquote> <p>John said "hello"</p> </blockquote> <p>how can I keep them in the generated image. Currently it turns to </p> <blockquote> <p>don\t </p> </blockquote> <p>Here is my code:</p> <pre><code>&lt;?php function formattextimg( $text, $width = 960, $color = array( 0, 0, 0 ),$bgcolor = array( 255, 255, 255 ), $font = 2 ) { $width = ( ( isset( $width ) &amp;&amp; is_numeric( $width ) ) ? ( ( $width &gt;= 100 ) ? (int)$width : 100 ) : 960 ); $text = str_replace( array( '&lt;b&gt;', '&lt;/b&gt;', '&lt;strong&gt;', '&lt;/strong&gt;' ), '|', $text ); $text_b = preg_split( '/\|/', $text, -1, PREG_SPLIT_OFFSET_CAPTURE ); foreach($text_b as $k =&gt; $tb){if($k%2!=0){$textbold[($tb[1]-1)]=$tb[0];}} $text = str_replace('|','',$text); for( $i = 0; $i &lt; strlen( $text ); $i++ ) { if( $string_c &gt;= ( $width - ( (int)(imagefontwidth( $font ) / 2 ) ) ) ) { $space = strrpos( $string, ' ' ); $string_sub = substr( $string, 0, $space ); $i = $i - ( strlen( $string ) - $space ) + 1; $strings[] = $string_sub; $string = ''; $string_c = 0; } $string .= $text{$i}; $string_c += imagefontwidth( $font ); } $strings[] = $string; $im = imagecreatetruecolor( $width, ( imagefontheight( $font ) * ( count( $strings ) ) ) ); imagesavealpha( $im, true ); $trans = imagecolorallocate( $im, $bgcolor[0], $bgcolor[1], $bgcolor[2] ); imagefill( $im, 0, 0, $trans ); $color = imagecolorallocate( $im, $color[0], $color[1], $color[2] ); $black = imagecolorallocate( $im, 0, 0, 0 ); foreach( $strings as $pos =&gt; $string ) { imagestring( $im, $font, 5, ( $pos * imagefontheight( $font ) ), $string, $color ); } $len = 0; foreach( $strings as $pos =&gt; $string ) { $len += ( strlen( $string ) + 1 ); if( count( $textbold ) &gt; 0 ) { foreach( $textbold as $cpos =&gt; $word ) { if( $cpos &lt;= $len ) { $wpos = strpos( $string, $word ); if( $wpos !== false ) { imagestring( $im, $font, ( $wpos * imagefontwidth( $font ) )+1, ( ( $pos ) * imagefontheight( $font ) ), $word, $color ); unset( $textbold[$cpos] ); } } } } } return $im; } header( 'Content-type: image/png' ); imagepng( formattextimg( $text,300,array( 255, 255, 255 ),array( 128, 128, 128 ),16 ) ); exit; ?&gt; </code></pre> <p>If that is not possible can someone please tell me how to remove the:</p> <blockquote> <p>'</p> </blockquote> <p>and </p> <blockquote> <p>"</p> </blockquote> <p>I tried:</p> <pre><code>$text=$_REQUEST['text']; $text=str_replace('"', "", $text); $text=str_replace("'", "", $text); </code></pre> <p>But it did not work.</p> <p>thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
